New York (Agencies): US President Barack Obama has called Lara Logan, the CBS chief foreign correspondent, who was sexually assaulted and beaten by a mob during her coverage of jubilation that ensued after President Hosni Mubarak's step-down.

"The President called her late this morning" and expressed concern for her condition, a family friend told 'The New York Post'.

The White House has asked Egypt to bring the perpetrators to justice.

"We believe that those responsible for these acts – and obviously there was other violence - need to be held accountable," Jay Carney, White House spokesperson said.

In a short news release on Tuesday, CBS said that the channel's team was surrounded by a mob of more than 200 people whipped into frenzy, in the midst of the celebration.

"In the crush of the mob, she was separated from her crew. She was surrounded and suffered a brutal and sustained sexual assault and beating before being saved by a group of women and an estimated 20 Egyptian soldiers," CBS said.

Logan, 39, then reconnected with the CBS team, returned to her hotel and returned to the US on the first flight the next morning.

More details emerged on Wednesday. Logan was sexually assaulted by thugs yelling, "Jew! Jew!” a source told The Post. And the day before, Logan had told a website that Egyptian soldiers were hassling her and her crew had accused them of "being Israeli spies."

Logan, however, is not Jewish.

Logan and CBS reportedly did not report the crime to Egyptian authorities nor did they check into a hotel in the country because they did not trust local security.

More than 140 journalists were attacked, detained and suffered some form of injury, according to the New York based Committee to Protect Journalists.
