SANA'A: A car bomb ripped through a rebel convoy in north Yemen Friday, killing two people including a suspected attacker in the second such attack this week, a rebel spokesman said. The blast, which also injured eight people, struck a string of cars in the rebel stronghold of Saada as they headed to a funeral for the spiritual leader of the Houthi rebel movement, named after their leaders' clan. Badr Al-Din Al-Houthi died of natural causes Thursday. One of those killed on Friday was a Houthi follower while the other is believed to have been an attacker, the Houthi spokesman said, although it could not be confirmed that the blast was a suicide attack. On Wednesday, a car bomb killed about 23 Houthi followers at a religious gathering in the northern Jawf province. The government condemned Wednesday's attack and said it would try to find out who was responsible. A February ceasefire between the rebels and the government halted a civil war that has raged on and off since 2004 and displaced around 350,000 people.
