Bahrain Rights Activist Says He Was Beaten After Attack on Protesters
By ROBERT MACKEY
A prominent human rights activist in Bahrain was briefly hospitalized on Friday night after the security forces attacked a protest in the capital, Manama.
Nabeel Rajab, the president of the Bahrain Center for Human Rights, told his lawyer that he was beaten by officers before being taken to Salmanyia hospital, which was taken over by the security forces last year after protesters were treated there. Late Friday, Mr. Rajab’s son Adam posted a close-up image of bruising on his father’s face on Twitter.
Video of the assault on the protesters posted online by activists shows that the security forces charged at them less than a minute after Mr. Rajab, standing at the head of the group, refused an officer’s order to disperse.
