NEW DELHI — In a sign of its growing confidence, Sri Lanka on Monday issued an ultimatum calling on Tamil rebels to surrender or perish after the army reportedly breached a major defensive barrier, paving the way for tens of thousands of civilians to make a run for it.
Troops captured an additional square-mile area of the rebels' shrinking terrain Monday, freeing about 19,000 civilians trapped by the fighting, while the navy freed 2,165 people and more fled in other directions, military spokesman Brig. Udaya Nanayakkara said.
By some reports, as many as 35,000 noncombatants fled the hotly contested battle zone.
None of the claims could be verified since the Sri Lankan government rarely allows independent media, civic or monitoring groups into the conflict area.
Government forces broke through part of a 7-mile-long barrier built by the rebels as they prepared for their last stand, military officials said. The breach allowed civilians to flee the area.
Last week, the government announced a 48-hour halt in its attacks against the rebels, formally known as the Liberation Tigers of Tamil Eelam, or LTTE, so some of the estimated 100,000 trapped civilians could leave the area. But few emerged.
The government blamed that on rebel leaders who, they and some international groups said, have been using noncombatants as human shields.
Sri Lanka has been under international pressure to address a growing humanitarian crisis. But the government has said repeatedly that any easing up of pressure will only help the Tigers to escape or regroup.
The civil war has raged for the last quarter century. In recent months, however, largely due to more aggressive tactics and a major increase in its ranks, the army has made significant gains, trapping most Tiger fighters in an area as small as 6.5 square miles on the island's northern coast.
"Militarily, [the Tamil fighters] appear to have lost their major artillery weapons, including 130mm [millimeter] guns and antiaircraft weapons," wrote Col. R. Hariharan, a retired Indian military intelligence official who served in Sri Lanka in the late 1980s, in a recent report. "Thus the security forces have overwhelmed the LTTE, not only physically, but also psychologically."
The Tigers seek a homeland for Tamils, a minority in the Sinhalese-dominated South Asian country. The United States and European Union have labeled the Tigers a terrorist group.
