Gulf states will press their efforts to broker an end to a political crisis in impoverished Yemen, the UAE foreign minister said on Tuesday. \"The unstable situation in Yemen is top of our agenda,\" UAE\'s Foreign Minister Shaikh Abdullah Bin Zayed Al Nahyan told a foreign ministers\' meeting of the six-nation Gulf Cooperation Council (GCC)  in the Saudi Red Sea city of Jeddah. \"We have made huge efforts to reconcile the opposing points of view and our efforts are certainly going to continue without let-up,\" Shaikh Abdullah said. The conflict has so far seen hundreds of people killed in five months of protests.

Saleh is currently being treated in a Saudi hospital for blast wounds he sustained in a bomb attack inside the presidential palace in Sana\'a. He was wounded as the long months of protests against his rule degenerated into street fighting in the capital between loyalist troops and dissident tribesmen. The president told King Abdullah Bin Abdul Aziz of Saudi Arabia Tuesday that his health was \"constantly improving,\" Yemen\'s official Saba news agency said. King Abdullah reiterated Saudi Arabia\'s support for a \"united, secure and stable Yemen,\" Saba added. Yemeni opposition activists had called on the Gulf ministers to \"stand with the will of the people in forming a transitional council that would achieve the aims of the revolution.\" The \"Youth Revolution\" activists, who have been organising nationwide protests against Saleh\'s rule since January, have called on Vice-President Abd Rabuh Mansur Hadi to form the proposed interim council immediately. Saleh\'s \"corrupt regime... has used your initiative as a cover for its crimes against us,\" the activists said in a statement, referring to a Gulf-brokered transition plan that the veteran ruler has stalled for months. Despite strong Western pressure, Saleh has repeatedly refused to sign up to the proposals under which he would hand power to the vice president within 30 days in exchange for a promise of immunity from prosecution. \"Yemen without this regime will be safer and more stable and committed to effective cooperation with its brothers and friends and to all regional and international agreements and accords it was part of,\" the activists\' declared. Tens of thousands of people demonstrated in the Yemeni capital on Tuesday against Saleh\'s return. \"He will not return, the traitor to his people will not return,\" they shouted. Similar rallies were held in other cities across Yemen. Yemen\'s General Union of Chambers of Commerce and Industry warned of a \"total collapse\" of the nation\'s economy if the turmoil continued. It called on the international community to \"use all forms of pressure... to facilitate the transfer of power in Yemen in order to fill the political, security and economic vacuum the country is currently suffering from.\" In Washington meanwhile, a top US State Department official said the US was still cooperating with Yemen in the fight against Al Qaida despite the crisis. \"We think that counterterrorism is not about one man, it\'s about national interest,\" Daniel Benjamin, coordinator for counterterrorism at the State Department said. Militants seize parts of Yemen Meanwhile, security officials said that militants have seized parts of a southern city in Yemen in a surprise dawn attack. The officials say the militants who attacked the city of Houta on Wednesday are believed to include members of Al Qaida. They are now in control of several neighbourhoods in the city, which is the provincial capital of Lahj province.
