ADEN, Sep 21, 2010 (AFP) - Al-Qaeda militants are using residents as human shields in the southern Yemeni town of Hota, where they are besieged by government forces, a Yemeni official said on Tuesday.

"Al-Qaeda elements are preventing residents from leaving Hota to use them as human shields," a security official who spoke on condition of anonymity told AFP.

A government siege of Hota, seeking to dislodge the militants, is now in its fourth day, and thousands of residents have already fled.

Out of roughly 20,000 people in Hota, in Shabwa province, 8,000-12,000 have managed to get out, said a preliminary Yemeni Red Crescent report released on Tuesday.

On Monday, Al-Qaeda members killed a tribal leader, Abdulwahed al-Mansur, and wounded a woman and two children, said Abdullah Ateq, chief administrator for the Mayfa district, which includes Hota.

He added that sporadic clashes occurred on Tuesday, but government forces, which received reinforcements from Sanaa, "have not yet managed to enter Hota" and are about two kilometres (1.2 miles) from the centre of town.

Between 80 and 100 suspected Al-Qaeda militants are in the town and the mountainous areas overlooking it, a local official said.

A tribal mediation effort seeking an end to hostilities and the "surrender of the terrorists" was unsuccessful, almotamar.com, the website of Yemeni President Ali Abdullah Saleh's party, on Tuesday quoted Shabwa Governor Ali Hassan al-Ahmadi as saying.

"These terrorists are determined to continue on the path of death," Ahmadi said, adding that government forces "will clear the region of these elements and will not allow them to escape."

While the situation for residents still in Hota is dangerous, those who fled also face a tough road.

"I am living with no shelter, like hundreds of other refugees, without any aid from authorities or charities," said Adnan Mohammed Ali, a refugee in Kharma, three kilometres (1.8 miles) from Hota.

"People need help, said Hussein bin Abdullah Bahanan, a tribal leader from Hota who was reached by telephone in Bureika, a village in the area where he is currently living.

In its interim report, the Red Crescent said the refugees are in need of food, blankets, and medical supplies.
