Colombo:
Air force jets attacked a rebel intelligence base deep in northern Sri Lanka early on Wednesday, stepping up a punishing wave of airstrikes a day after Tamil Tiger fighters launched a surprise attack on a military base, the military said.
The Tamil Tigers said the bombs hit a civilian settlement in the rebel's administrative capital of Kilinochchi, destroying 12 houses.
The air force has conducted a series of bombing raids over rebel-held territory in the north since the Tamil Tigers attacked a military complex in Vavuniya early on Tuesday.
The military said that the attack killed 13 troops, one civilian and 11 of the attackers. The rebels said at least 20 government troops and 10 rebel fighters were killed.
The raid also injured two Indian technicians who were servicing a radar system at the base, said Dinkar Asthana, a spokesman for the Indian High Commission in Colombo.
",They are out of danger and they are being treated,", he said, providing no further details.
Separate battles between the two sides killed 19 rebels and two soldiers, the military said.
