LINCOLN UNIVERSITY, Pa. (AP) — Gunfire erupted during outdoor festivities at Pennsylvania’s Lincoln University late Saturday, killing one person and wounding six others as students and alumni celebrated homecoming at the historically Black school, authorities said.
A person who had a firearm was detained, and officials are investigating the possibility that there was more than one shooter but don’t believe there is any active threat to the campus, Chester County District Attorney Christopher de Barrena-Sarobe said during a brief news conference early Sunday.
“We don’t have a lot of answers about exactly what happened," he said. “What I will tell you is that today we’re operating as if this is not an incident where someone came in with the design to inflict mass damage on a college campus.”
Authorities say the shooting took place at around 9:30 p.m. outside a large building called the International Cultural Center, where tents and tables were set up for tailgating and socializing after a football game earlier in the day.
“It was a chaotic scene, and people fled in every direction," the district attorney said. He urged anyone with video from the scene or other information that could help the investigation to contact the FBI.
Authorities weren’t sharing details about the victims, including their conditions or where the injured were being treated.
The campus is about 45 miles (70 kilometers) southwest of Philadelphia. Chester County detectives are leading the investigation, with support from state police and the FBI.
Pennsylvania Gov. Josh Shapiro said on X that he was briefed on the shooting and offered the support of his administration and family.
“Join Lori and me in praying for the Lincoln University community,” he said.
Lincoln University Police Chief Marc Partee said the shooting devastated the school's community on what was supposed to be a joyous day focused on the school’s legacy.
“If there was another word to describe that, that’s more impactful, I would use it,” he said, “but ‘devastated’ is a start.”

WASHINGTON (AP) — President Donald Trump made new threats to escalate strikes in Iran on Sunday, a day after U.S. forces pulled off a dramatic rescue of an aviator whose plane fell behind enemy lines after Iran had downed it days earlier.
Iran showed no signs of backing down, striking economic and infrastructure targets in neighboring Gulf Arab countries even as Trump demanded Iran reopen the Strait of Hormuz.
In an expletive-laden post Sunday morning, Trump expanded upon earlier threats, promising strikes on Iran’s power plants and bridges. He vowed the “crazy bastards” would be “living in Hell” if the waterway isn’t opened to marine traffic by Tuesday. He ended his post with “Praise be to Allah.”
The U.S. airman's extraction followed a search-and-rescue operation after the Friday crash of the F-15E Strike Eagle, as Iran also promised a reward for anyone who turned in an “enemy pilot.” Trump said the servicemember was injured but in stable condition.
A second crew member was rescued earlier.
The fighter jet was the first American aircraft to have crashed in Iranian territory since the U.S. and Israel launched the war, striking Iran on Feb. 28. Both sides have threatened and hit civilian targets, bringing warnings of possible war crimes. The war has killed thousands, shaken global markets, cut off key shipping routes and spiked fuel prices.
As Iran continues to exert control over the Strait of Hormuz, Trump, in an earlier social media post, threatened to unleash “all Hell” if it isn’t opened by Monday. He has issued such threats before and extended them when mediators have claimed progress toward ending the war on agreeable terms.
The threats came after Trump said last week that the U.S. had “decimated” Iran and would finish the war “very fast.” Two days later, Iran shot down two U.S. military planes, showing the ongoing perils of the bombing campaign and the ability of a degraded Iranian military to continue to hit back.
The other jet to go down was a U.S. A-10 attack aircraft. Neither the status of the crew nor exactly where it crashed was immediately known.
On Sunday, Iran’s state TV aired a video showing what it claimed were parts of American aircraft shot down by Iranian forces, along with a photo of thick, black smoke rising into the air. The broadcaster said Iran had shot down an American transport plane and two helicopters that were part of the rescue operation.
However, a regional intelligence official briefed on the mission told The Associated Press that the U.S. military blew up two transport planes due to a technical malfunction, forcing it to bring in additional aircraft to complete the rescue. The official spoke on condition of anonymity to discuss the covert mission.
Iran’s military joint command on Sunday claimed that four U.S. aircraft were destroyed during the rescue operation and warned of stepping up retaliatory attacks on regional oil and civilian infrastructure if the U.S. and Israel attacked such targets in the Islamic Republic, according to state television.
“We once again repeat: if you commit aggression again and strike civilian facilities, our responses will be more forceful,” a spokesman said in comments run by IRNA news agency.
In Kuwait, Iranian drone attacks caused significant damage to power plants and a petrochemical plant. They also put a water desalination station out of service, according to the Ministry of Electricity. No injuries were reported, the ministry said.
In Bahrain, a drone attack caused a fire at one of the national oil company’s storage facilities and a state-run petrochemical plant, the kingdom’s official news agency said.
In the United Arab Emirates, authorities responded to fires at a petrochemical plant in Ruwais that they said were caused by intercepted debris, halting operations.
The strikes came a day after Israel struck a petrochemical plant in Iran that Prime Minister Benjamin Netanyahu said generated revenue that it had used to fund the war.
The petrochemical industry is a key sector in many Gulf states. Plants in Bahrain, Kuwait, the UAE and Iran convert oil and gas into products like plastics, polymers and fertilizer, bringing in billions in export revenue.
Trump renewed his threats for Iran to open up the Strait of Hormuz by Monday or face consequences, writing Saturday in a social media post: “Remember when I gave Iran ten days to MAKE A DEAL or OPEN UP THE HORMUZ STRAIT. Time is running out — 48 hours before all Hell will reign down on them.”
The waterway is a critical chokepoint for commerical trade, especially oil and gas moving from the Persian Gulf to Europe and Asia. Disruptions there have injected volatility into the market and pushed oil and gas-importing countries to seek alternative sources.
“The doors of hell will be opened to you” if Iran’s infrastructure is attacked, Gen. Ali Abdollahi Aliabadi with the country’s joint military command said late Saturday in response to Trump’s renewed threat, state media reported. In turn, the general threatened all infrastructure used by the U.S. military in the region.
Pakistan’s Foreign Ministry spokesperson, Tahir Andrabi, told AP that his government’s efforts to broker a ceasefire are “right on track” after Islamabad last week said that it would soon host talks between the U.S. and Iran.
Mediators from Pakistan, Turkey and Egypt were working to bring the U.S. and Iran to the negotiating table, according to two regional officials.
The proposed compromise includes a cessation of hostilities to allow a diplomatic settlement, according to a regional official involved in the efforts and a Gulf diplomat briefed on the matter. They spoke on condition of anonymity to discuss closed-door diplomacy.
More than 1,900 people have been killed in Iran since the war began.
In Gulf Arab states and the occupied West Bank, more than two dozen people have died, while 19 have been reported dead in Israel and 13 U.S. service members have been killed. In Lebanon, more than 1,400 people have been killed and more than 1 million people have been displaced. Ten Israeli soldiers have died there.
