Explosion Outside Aden Government Building in Yemen Kills 4: Witnesses

ADEN: An improvised explosive device detonated next to the governor's office in the southern Yemeni city of Aden on Thursday, a local official and witnesses said, killing four people and wounding 11, several of them critically.

The blast underscores instability in Yemen's second largest city a month after fighters loyal to the country's exiled government seized it from Iran-allied Houthi forces with heavy backing by rich Gulf Arab states.
