An explosive device blew up on Monday at the Economy Ministry in the Yemeni capital Sanaa, killing one person and injuring another three. The Kuwaiti news agency Kuna reported that the attackers fled the scene in a vehicle immediately after the explosion. Police officers gave chase, but failed to capture the militants. Eyewitnesses say they saw a vehicle with two people on board drive up to the ministry building and one of them then threw a hand grenade out of the window.
