A Yemeni anti-government demonstrator protest against President Ali Abdullah Saleh More than 200 suspected Al Qaida gunmen have wrested control of the south Yemen city of Zinjibar after heavy fighting with security forces that left 16 dead, an official said Sunday. The Yemeni opposition immediately accused embattled President Ali Abdullah Saleh of having allowed Zinjibar, capital of Abyan province, to fall to the gunmen to raise fears concerning Al Qaida and boost his flagging international support.
The suspected Al Qaida fighters \"were able to gain control of the city of Zinjibar ... and took over all government facilities\", except for the headquarters of the 25th mechanised brigade, which is besieged by militants, the security official said.
Witnesses said that the gunmen were battling members of the besieged brigade Sunday morning.
\"We will fight until the last bullet, and we will not surrender to the gunmen who killed our colleagues,\" an officer from the brigade said when reached by telephone.
Residents reported heavy fighting in the city on Friday and Saturday, and said the attackers had freed dozens of prisoners from the main jail in Zinjibar.
One witness said on condition of anonymity that the gunmen executed soldiers who surrendered, and that residents were not able to bury them. Dozens of families fled towards Aden, the main city in the south, among them Nazir Ahmad Said, who said he left because \"the city is under the control of gunmen who say they are from Al Qaida\".


\"Saturday morning, the gunmen called on residents by loudspeaker to go out and reopen their shops, but few answered the call because they are afraid,\" he added.
The security official estimated that more than 200 militants had attacked the city.
\"The lack of concern from the authorities is unfortunate,\" he said, adding that \"the leadership in Abyan province left the area before it exploded\". He was among the last security officials to quit the city, he said.
Five soldiers and a civilian were killed on Friday, two other security officials said, while residents of Zinjibar said they found the bodies of 10 soldiers, bringing the toll from the fighting there to at least 16.
One of the officials said that another two soldiers were killed Friday in clashes with suspected Al Qaida fighters in the town of Loder, also in Abyan province.
In a statement, the Common Forum parliamentary opposition coalition accused Saleh of having \"delivered Zinjibar to armed groups that he has formed and armed, to continue to utilise the spectre of Al Qaida to frighten regional and international parties\".
It denounced \"the criminal plotting of Ali Abdullah Saleh\" and reiterated its call for \"the immediate departure\" of the president.
Saleh has since January faced protests calling for him to quit office after 33 years in power.
On May 22, he refused to ink a Gulf Cooperation Council-sponsored accord that would have seen him cede power within 30 days in exchange for immunity from prosecution.
