Suicide bombers have attacked two mosques in Yemen’s capital, Sanaa, killing at least 77 people and wounding 121 others, medics say.
Worshippers were attending noon prayers at the Badr and al-Hashoosh mosques when at least three attackers struck.
The mosques are used mainly by supporters of the Zaidi Shia-led Houthi rebel movement, which controls Sanaa.
Islamic State (IS), which set up a branch in Yemen in November, said it was behind the attacks.
If confirmed, the attacks would be the first carried out by IS in Yemen.
There are also severe tensions between the Houthi rebels and various powerful, armed elements in Yemen, including militants from al-Qaeda.
Blood ‘running like river’
Witnesses said at least two suicide bombers attacked the Badr mosque, in the south of Sanaa.
One entered the building and detonated his explosive device among dozens of worshippers, the witnesses added. Survivors then sought to escape through the main gates, where the second bomber was waiting.
