Sanaa: An explosion rocked a mosque in Yemen's rebel-held capital on Thursday during prayers for the Muslim holiday of Eid al-Azha, witnesses said.

The blast happened in the Balili mosque near a police academy in Sanaa, which is controlled by the Huthi Shia insurgents, according to witnesses, some of whom reported seeing dead and wounded. 

The Yemeni capital has been shaken by a string of bombings of Shiite mosques in recent months claimed by the Islamic State jihadist group. The radical Sunni Muslim group considers Shiites to be heretics and has also claimed bombings of mosques in Kuwait and Saudi Arabia. 

The Iran-backed Huthi rebels have seized several regions of Yemen including Sanaa which they overran a year ago. Pro-government forces backed by Saudi-led air strikes have recently managed to wrest back some southern provinces, including Yemen's second city of Aden.
