The Tamil Tiger rebels on Saturday called a defiant air raid on the Sri Lankan capital a success, despite the planes missing their stated targets the night before. The LTTE in a news release said the raid targeted Sri Lanka's air force headquarters in Colombo and airbase at the international airport, pro-rebel web site www.TamilNet.com reported. Air defenses were stepped up on fears the Liberation Tigers of Tamil Eelam (LTTE) would try more suicide attacks as they steadily lose terrority to advancing government forces. The surprise attack late on Friday by two small Tiger air craft set off hails of anti-aircraft fire across Colombo. One slammed into the main government tax office in central Colombo, killing at least two people and wounding 53, the military said. The other plane was shot down and crashed in a marsh outside the international airport - site of the Tiger air wing's first strike in 2007.
