A besieged government and its supporters retaliated fiercely against journalists covering the months of popular protests that sought an end to President Ali Abdullah Saleh's rule. Authorities detained local journalists, expelled international reporters, and confiscated newspapers in an effort to silence coverage, while government supporters and plainclothes agents assaulted media workers in the field. Two journalists covering anti-government protests were killed by gunfire, one by security forces who fired live ammunition to disperse a demonstration, the other by a sniper suspected to have been acting on behalf of the government. The government singled out Al-Jazeera in a months-long effort to silence its coverage. In March, plainclothes agents raided the station's Sana'a bureau, confiscating equipment. The raid followed the expulsion of two Al-Jazeera correspondents. Days later, authorities ordered Al-Jazeera's offices shut and its journalists stripped of accreditation. Other newsrooms were under direct fire. Armed men in civilian clothes tried to storm the offices of the independent daily Al-Oula, seriously wounding an editorial trainee, while military forces shelled the Yemeni satellite broadcaster Suhail TV, whose staff endured numerous other threats and detentions. In a rebuke to the regime, the 2011 Nobel Peace Prize was awarded to renowned Yemeni press freedom activist Tawakul Karman, chairwoman of Women Journalists Without Chains, along with two female African leaders.
