Yemeni officials say two suicide bombings — one in the capital, Sanaa, the other in the country's south — have killed at least 50 people.

Security and hospital officials say 30 people died when a suicide bomber set off his explosives in central Sanaa on Thursday morning, targeting a gathering of supporters of the rebel Shiite Houthi movement that recently overran the city.

The second bombing took place at the outskirts of the southern city of Mukalla, where a suicide car bomber rammed his car against a security outpost, killing at least 20 soldiers.

There was no immediate claim of responsibility for either attack, which bore the hallmarks of al-Qaida. The officials spoke on condition of anonymity because they were not authorized to speak to the media.
