CBS News chief foreign correspondent Lara Logan was sexually assualted while covering the protests in Egypt, the network said on Tuesday. The assualt, which CBS described as "brutal," happened while Logan and a crew were covering the celebrations in Cairo's Tahrir Square last Friday after Egyptian President Hosni Mubarak resigned. 

The network said in a statement that Logan and her team, including security forces, were surrounded by a mob of about 200 people. The statement went on to say that Logan was separted from her crew and then "suffered a brutal and sustained sexual assault and beating." CBS said she was saved by a group of women and about 20 Egyptian soldiers. 

She was then reunited with her CBS team at their hotel and returned to the United States on Saturday, the network said. Logan is currently recovering in a hospital. CBS did not reveal the extent of Logan's injuries.

The network also said it would not provide futher comment.

A week prior to the assault, Logan had been detained by Egyptian police outside the Israeli embassy. She also had reported that journalists were having trouble filing stories. "The army just shifted dramatically to a much more aggressive posture, and they have absolutely prevented us from filming anywhere," she said at the time, describing it as a " a very frightening experience and one that was repeated throughout the day for us."

Time noted that when Logan was detained: "She has been filing reports from the country since Jan. 31. She went on to note that even when Logan and crew left their hotel without cameras, they were followed relentlessly by officials."

The 39-year-old Logan has been a reporter for CBS News since 2002. She has reported from numerous foreign locations, including following U.S. troops into combat in Iraq and Afghanistan.
