Sri Lankan troops are fighting inside Elephant Pass, the strategic gateway to the Jaffna Peninsula held by the separatist Tamil Tiger rebels, Reuters quoted the government as saying on Friday. "We haven't captured it. We are moving in and fighting is going on," defense spokesman Keheliya Rambukwella, who is also a minister, told Reuters. Some media reports said it had been captured, but Rambukwella said that was premature.
