An explosion on a bus in the Yemeni capital Sanaa has killed at least two soldiers and injured ten more.

The blast happened at a time of increased violence in the country, with bombings in Sanaa and tribal battles in the north.

Authorities are looking into whether the explosion was caused by a bomb hidden on the bus, a roadside device or a suicide bomber.
