A Yemeni security official says a top police commander has been killed in a car bombing, the latest in a series of attacks in south Yemen during the popular movement to oust longtime President Ali Abdullah Saleh.

The official says at least two other people were wounded in the blast Friday in the coastal city of Aden.

On Thursday, an air strike killed three suspected militants and injured six other people in southern Yemeni village of Shaqra. The village is part of a region where Yemeni security forces have been waging ongoing battles against al-Qaida-linked militants.

President Saleh's government has been trying to oust the militants from their southern strongholds.

Mr. Saleh has said several times he is willing to accept a proposal from the Gulf Cooperation Council that would give him immunity from prosecution if he handed power to a deputy within 30 days.

In each case, he has backed down without signing the measure.
