Broadcast journalists were increasingly targeted — detained, harassed or beaten — amid the unrest in Egypt Thursday, among them CBS anchorwoman Katie Couric and a Fox News Channel crew.

Meantime, sources told Time magazine that Lara Logan, chief foreign affairs correspondent for CBS News, was held along with her crew by Egyptian police outside Cairo's Israeli embassy. Couric wrote on Twitter that she and her crew came under attack by "very hostile" supporters of President Hosni Mubarak and that they "wouldn't let us shoot video."

Fox News reported that their correspondent Greg Palkot and his cameraman, Olaf Wiig, were severely beaten, but have been released from a Cairo hospital.

Anderson Cooper to continue reporting from Egypt after attack

Christine Amanpour detailed in an ABC News story that an angry mob had surrounded and chased her and her film crew into their car. "Some of the protesters kicked in the car doors and broke our windshield as we drove away," she said.

On Wednesday, CNN's Anderson Cooper said that he and his crew were punched in their heads in Cairo's Tahrir Square by a mob who thought the CNN team was taking photos. Despite the attack, the 360 host says he will continue to report from Egypt. On Thursday, Cooper tweeted about his vehicle being attacked, adding: "My window smashed. All OK."

Nicholas Kristof of The New York Times also tweeted that police were aggressively raiding hotels, "looking for journalists. Be careful!"
