Following a string of victories, the military backed the rebels into a small strip of land on the northeastern coast, where the Red Cross estimates 250,000 civilians are also trapped. The military has accused the rebels of holding the civilians as human shields and called for noncombatants to flee to government-controlled areas. The rebels have accused the government of indiscriminately shelling the war zone, leading to increasing civilian casualties. On Monday morning, more than 800 civilians had crossed the front lines and were being searched by soldiers before being sent to camps farther south, military spokesman Brig. Udaya Nanayakkara said. When the attacker was frisked, she set off the bomb she was wearing, killing 24 people and injuring 20 others, he said. The LTTE is now desperate because they dont have any control over the civilians now, Nanayakkara said, calling the rebels by the initials of their formal name, the Liberation Tigers of Tamil Eelam. They wanted to stop these people coming in. The attack appeared aimed at one of the militarys weak points, the processing of the masses of civilians trying to flee the area. It also highlighted concerns that the rebels were trying to blend in with the civilian population, so they can fight on using insurgent tactics. The military has said the flow of civilians out of the war zone has increased in recent days, with 4,700 fleeing Sunday, bringing the total number of noncombatants to escape the war zone to 20,000 this year, Nanayakkara said. With most communication to the north severed, the rebels could not be reached for comment. The rebels have been accused of more than 200 suicide attacks and are listed as a terror group by the United States and the European Union. The Tamil Tigers have been fighting since 1983 for a separate state for the nations ethnic Tamil minority after decades of marginalization at the hands of governments controlled by the Sinhalese majority. More than 70,000 people have been killed in the fighting. Also Monday, the air force hit a camouflaged building inland where the rebels sea wing hid its craft, Nanayakkara said. The place was destroyed, he said. The military also reported killing 34 rebels who tried to break through the front lines Saturday in an armored truck. Ben Roethlisberger Authentic Jersey.
