(USA Today) -- A young American in Egypt was killed Friday in Alexandria while photographing clashes between opponents and supporters of President Mohammed Morsi.
State Department spokeswoman Marie Harf identified the victim as Andrew Pochter.
Kenyon College in Gambier, Ohio, says in a statement on its website that Pochter was a 21-year-old student from Chevy Chase, Md., working in Egypt as an intern for a non-profit education organization.
There were conflicting reports about how Pochter was killed.
Reuters reported that Gen. Amin Ezz Eddin, a senior Alexandria security official, said he was stabbed in the chest in Sidi Gabr Square while using his mobile phone camera near an office of Morsi's Muslim Brotherhood, which opponents had sent on fire. He died in a military hospital.
But an unidentified medical official told the Associated Press the man died form a gunshot wound
Al-Arabiya said the victim was a teacher, the BBC said he was a journalist and Ahram Online called him a photojournalist.
The U.S. Embassy said it was trying to confirm the reports.
Hours after the killing, the State Department warned Americans not travel to or within Egypt unless it was essential, and the U.S. Embassy reduced non-emergency personnel and family members.
"U.S. citizens are urged to remain alert to local security developments and to be vigilant regarding their personal security," the updated travel warning said.
One Egyptian also died in the Alexandria clashes and 88 others injured, according to the health ministry. Riot police and army helicopters were called in to try to end the violence. Most of the protesters in Egypt's second-largest city had dispersed by midnight, media reported.
Violence erupted in other parts of the country, including Cairo, where hundreds of thousands of Egyptians turned out to show support for Morsi or to call for him to resign after a year in office. Muslim Brotherhood offices were attacked in Gharbiya, Daqahliyah and Kafr el-Sheikh, Egyptian media reported.
In Tahrir Square, a foreign woman taking photos and video was attacked, Ahram Arabic reported.
The woman was beaten and dragged after one group of protesters asked her to leave because she was not Egyptian. Other demonstrators said she had a right to stay, and a fierce argument ensued.
The woman, whose nationality was not immediately identified, suffered unspecified injuries and was helped away, the news outlet said. It wasn't clear whether she was attacked by pro- or anti-government protesters.
At least six Egyptians have died during days of clashes ahead of nationwide protests Sunday demanding that Morsi be removed.
Anti-American sentiments were seen in Cairo's Tahrir Square and in Suez, according to eyewitnesses. Morsi supporters accused opponents of working with the United States and Israel.
In Cairo, protesters carried images of of U.S. Ambassador Ann Paterson with a red 'X' over her face, an Al-Jazeera reporter said. In Suez, demonstrators carried banners with slogans against her.
Nationwide rallies are planned for Sunday.
