HAMPTON, S.C. (AP) — Authorities in South Carolina are investigating a shooting at a nightclub early Sunday that wounded at least nine people. It was the second mass shooting in the state and the third in the nation during the Easter holiday weekend.

The shootings in South Carolina and one in Pittsburgh, in which two minors were killed early Sunday, also left at least 31 people wounded.

No one was reported killed in the violence at Cara’s Lounge in Hampton County, roughly 80 miles (130 kilometers) west of Charleston, according to an email from South Carolina’s State Law Enforcement Division, which is investigating the shooting. A phone call to the nightclub was not answered.

In Pittsburgh, two male youths were killed and at least eight people wounded when shots were fired during a party at a short-term rental property. The “vast majority” of the hundreds of people at the party were underage, the city’s Police Chief Scott Schubert told reporters. The Allegheny County Medical Examiner’s Office identified the two victims as Jaiden Brown and Mathew Steffy-Ross, both 17.

Investigators believe there were multiple shooters, and Schubert said police were processing evidence at as many as eight separate crime scenes spanning a few blocks around the rental home.

The two shootings come just a day after gunfire erupted at a busy mall in the South Carolina state capital of Columbia, about 90 miles (145 kilometers) north of Sunday’s nightclub shooting. Nine people were shot, and five people sustained other kinds of injuries while trying to flee the scene at the Columbiana Centre, Columbia Police Chief W.H. “Skip” Holbrook said Saturday. The victims ranged in age from 15 to 73. None faced life-threatening injuries.

“We don’t believe this was random,” Holbrook said. “We believe they knew each other and something led to the gunfire.”

The only person arrested in the mall shooting so far is Jewayne M. Price, 22, one of three people initially detained by law enforcement as a person of interest. Price’s attorney, Todd Rutherford, told news outlets Sunday that his client fired a gun at the mall, but in self-defense. Rutherford said Price faces a charge of unlawfully carrying a pistol because he legally owned his gun but did not have a permit to carry a weapon.

Columbia police said on Twitter that a judge agreed Sunday to let Price leave jail on a $25,000 surety bond. He was to be on house arrest with an ankle monitor, police said.

“It was unprovoked by him. He called the police, turned himself in, turned over the firearm that was used in this, and gave a statement to the Columbia Police Department,” Rutherford said, according to WMBF-TV. “That is why he got a $25,000 bond.”

Police said the judge will allow Price to travel from home to work during certain hours each day. Price is forbidden from contacting the victims and anyone else involved in the shooting.

South Carolina residents age 21 or older can get a weapons permit, which as of last year allows them to carry weapons openly or concealed. They must have eight hours of gun training and pass a background check that includes fingerprinting.

The three Easter weekend mass shootings are in addition to other gun violence in recent days. Last week, a gunman opened fire in a New York subway car, wounding 10 people. A suspect was arrested the next day. Earlier this month, six people were killed and 12 others wounded in Sacramento, California, during a gunfight between rival gangs as bars closed in a busy downtown area just blocks from the state Capitol.

One week ago, a shooting inside a crowded nightclub in Cedar Rapids, Iowa, left a man and a woman dead and 10 people wounded. And last month, 10 people were shot at a spring break party in Dallas and several others were injured as they tried to escape the gunfire.

KYIV, Ukraine (AP) — A day after Moscow suffered a stinging symbolic defeat with the loss of the flagship of its Black Sea fleet, Russia’s Defense Ministry promised Friday to ramp up missile attacks on the Ukrainian capital in response to Ukraine’s alleged military “diversions on the Russian territory.”

The threat of intensified attacks on Kyiv came after Russian authorities accused Ukraine of wounding seven people and damaging about 100 residential buildings with airstrikes on Bryansk, a region that borders Ukraine. Authorities in another border region of Russia also reported Ukrainian shelling Thursday.

Kyiv has gradually displayed some signs of pre-war life after Russian troops failed to capture the city and retreated to focus on a concentrated assault in eastern Ukraine, leaving evidence of possible war crimes in their wake. A renewed bombardment could return the capital’s residents to sheltering in subway stations and the steady wail of air raid sirens.

Ukrainian officials have not confirmed striking targets in Russia, and the reports by Russian authorities could not be independently verified. However, Ukrainian officials claimed their forces struck a key Russian warship with missiles on Thursday. If true, the claim would represent an important victory.

The guided-missile cruiser Moskva, named for the Russian capital, sank while being towed to port Thursday after suffering heavy damage under circumstances that remained in dispute. Moscow acknowledged a fire on board but not any attack. U.S. and other Western officials could not confirm what caused the blaze.

The Moskva had the capacity to carry 16 long-range cruise missiles, and its removal reduces Russia’s firepower in the Black Sea. If Ukrainian forces took out the vessel, the Moskva likely represents the largest warship to be sunk in combat since the Falklands War. A British submarine torpedoed an Argentine navy cruiser called the ARA General Belgrano during the 1982 conflict, killing over 300 sailors on board.

The Russian warship’s loss in an invasion already widely seen as a historic blunder also was a symbolic defeat for Moscow as its troops regroup for an offensive in eastern Ukraine after retreating from the Kyiv region and much of the north.

In his nightly address Thursday, Ukrainian President Volodymyr Zelenskyy said the people of his country should be proud of having survived 50 days under attack when the Russian invaders “gave us a maximum of five.”

Zelenskyy did not mention the Moskva by name, but while listing the ways Ukraine has defended against the onslaught, mentioned “those who showed that Russian warships can sail away, even if it’s to the bottom” of the sea. It was his only reference to the Moskva.

News about the flagship overshadowed Russian claims of advances in the southern port city of Mariupol, where Moscow’s forces have been battling the Ukrainians since the early days of the invasion in some of the heaviest fighting of the war — at a horrific cost to civilians.

Dwindling numbers of Ukrainian defenders in Mariupol are holding out against a siege that has trapped well over 100,000 civilians in desperate need of food, water and heating. David Beasley, executive director of the U.N. World Food Program, told The Associated Press in an interview Thursday that people were being “starved to death” in the besieged city.

Mariupol’s mayor said this week that more than 10,000 civilians had died and the death toll could surpass 20,000. Other Ukrainian officials have said they expect to find evidence of atrocities committed against civilians like the ones discovered in Bucha and other towns outside Kyiv once the Russians withdrew.

The Mariupol City Council said Friday that locals reported seeing Russian troops digging up bodies that were buried in residential courtyards and not allowing any new burials “of people killed by them.”

“Why the exhumation is being carried out and where the bodies will be taken is unknown,” the council said in a statement posted on the Telegram messaging app.

Mariupol’s capture is critical for Russia because it would allow its forces in the south, which came up through the annexed Crimean Peninsula, to fully link up with troops in the Donbas region, Ukraine’s eastern industrial heartland and the target of the looming offensive.

Moscow-backed separatists have fought Ukrainian forces in the Donbas since 2014, the same year Russia seized Crimea from Ukraine. Russia has recognized the independence of two rebel-held areas of the region.

Although it’s not certain when Russia will launch the full-scale campaign, a regional Ukrainian official said Friday that seven people died and 27 were injured after Russian forces opened fire on buses carrying civilians in the village of Borovaya, near the northeastern city of Kharkiv.

Ukrainian law enforcement agencies are working to establish the circumstances of the attack, Dmytro Chubenko, a spokesman for the regional prosecutor’s office, told Ukraine’s Suspilne news website.

Chubenko said that Ukrainian authorities had opened criminal proceedings in connection with a suspected “violation of the laws and customs of war, combined with premeditated murder.” The claims of an attack on civilian buses could not be independently verified.

The Russian Defense Ministry said Friday that Russian strikes in the Kharkiv region “liquidated a squad of mercenaries from a Polish private military company” of up to 30 people and “liberated” an iron and steel factor in Mariupol from “Ukrainian nationalists.” The claims could not be independently verified.

On Thursday, the Defense Ministry explained the damage to Russia’s Black Sea flagship by a fire had caused ammunition stowed on board to detonate. In addition to the cruise missiles, the warship also had air-defense missiles and other guns.

The ministry did not say what might have caused the blaze but reported that the “main missile weapons” were not damaged and the crew, which usually numbers about 500, abandoned the vessel. It wasn’t clear if there were any casualties.

Maksym Marchenko, the governor of Ukraine’s Black Sea region of Odesa, said Ukrainian forces struck the Moskva with two Neptune missiles and caused “serious damage.” The Neptune is an anti-ship missile that was recently developed by Ukraine based on an earlier Soviet design.

The missile’s launchers are mounted on trucks stationed near the coast, and, according to the Washington-based Center for Strategic and International Studies, can hit targets up to 280 kilometers (175 miles) away. That would have put the Moskva within range, based on where the ship was when the fire began.

Launched as the Slava in 1979, the cruiser saw service in the Cold War and during conflicts in Georgia and Syria, and helped conduct peacetime scientific research with the United States. During the Cold War, it carried nuclear weapons.

British defense officials said the Moskva’s loss would likely force Moscow to change how its naval forces operate in the Black Sea. In a social media post Friday, the U.K. Ministry of Defense said the ship, which returned to operational service last year after a major refit, “served a key role as both a command vessel and air defense node.”

Other Russian ships in the northern Black Sea moved farther south after the Moskva incident, a senior U.S. defense official said, speaking on condition of anonymity to discuss internal military assessments.

Russia invaded Ukraine on Feb. 24 and has lsuffered thousands of military casualties. The conflict has killed untold numbers of Ukrainian civilians and forced millions more to flee.

It has also further inflated prices at grocery stores and gasoline pumps, while dragging on the global economy. The head of the International Monetary Fund said Thursday that the war helped push the organization to downgrade economic forecasts for 143 countries.
