A powerful suicide bombing in the Yemeni capital on Thursday killed at least 43 people in an attack on supporters of Shiite insurgents who have overrun the city, medics said.
In another attack in southeastern Yemen, a suspected al Qaeda suicide bomber killed 20 soldiers at an army checkpoint, the military said, revising an earlier toll of 10 dead.
Medics said dozens were also wounded in the Sanaa blast — the largest in the capital since a May 2012 Qaeda attack on an army parade killed around 100 people.
The blast struck Sanaa`s Al-Tahrir square as supporters of the rebels were preparing to stage a protest, rebel sources said.
Medics at nearby Police Hospital sent urgent calls for doctors to help cope with the high number of casualties.
A rebel source earlier said 21 people were killed in the attack.
Witnesses said a suicide bomber detonated an explosive belt at a checkpoint at the entrance to the protest site, leaving steel balls strewn at the scene.
Supporters of the rebels, known as Huthis, gathered after the explosion chanting slogans demanding the fall of President Abdrabuh Mansur Hadi.
