Yemen's Shiite rebels say a pair of suicide bombers attacked two mosques in the capital Sanaa.

A report on the rebel-owned Al-Masirah TV channel says the bombers attacked the Badr and al-Hashoosh mosques during midday prayers on Friday. Both mosques are controlled by Shiite rebels, known as Houthis. There was no immediate casualty report.

The blast comes a day after intense gun battles in the southern city of Aden, between rival troops loyal to Yemen's former and current president, left 13 dead.

The Houthis, who are allies to former President Ali Abdullah Saleh, have controlled the capital last year since September; earlier this year they put Abed Rabbo Mansour Hadi, the western-backed president, under house arrest. Hadi has since fled to Aden and maintains he is still the legitimate president.
