Blast near military academy in Sanaa: security sources

A bomb exploded near a military academy in the Yemeni capital Sanaa on Monday evening, security sources told Reuters, in a neighborhood that is a main stronghold of Shiite Houthi fighters.

It was unclear whether the blast had caused any casualties.

Security in Yemen has frayed since the Houthis formally took power in the capital this month, raising fears of an all-out civil war and of an increase in attacks by radical Sunni militants loyal to Al Qaeda.
