COLOMBO, Nov 23 (Reuters) - Sri Lanka's Tamil Tigers said on Thursday they were engaged in fierce fighting with the army in no-man's land in the island's restive east, with government troops with tanks trying to breach their defence lines. "There is an intense confrontation going on," Liberation Tigers of Tamil Eelam (LTTE) military spokesman Rasiah Ilanthiraiyan told Reuters by telephone from the rebels' northern stronghold. The military said it had no details of any confrontation in the east.
