Sri Lankan soldiers arrive at the site of a military helicopter gunship crash following a dawn attack in Anuradhapura October 22, 2007. The Tamil Tigers' air wing bombed a north Sri Lanka air force base before dawn on Monday, the military said, while the Tigers said suicide fighters mounted their biggest ground assault since the two-decade civil war began. The rebel air strike in the north-central district of Anuradhapura comes months after the Tigers' first ever air attacks using light aircraft smuggled into the country in pieces, and as near daily land, air and sea clashes occur.
