An American envoy says Washington has asked the European Union to follow its lead and list Sri Lanka's Tamil Tiger rebels as terrorists.

A U.S. embassy spokesman in Colombo says visiting Deputy Assistant Secretary of State Donald Camp made the remark at the end of his visit to the island nation.

Camp said the United States believes steps should be taken to cut off the rebels' financial supplies and weapons procurement.

Earlier Tuesday, the U.S. diplomat met with Sri Lanka's foreign and defense ministers and the Tamil National Alliance party leaders, seen as a proxy for the rebels.  He urged the two sides to return to peace talks.

His call for peace came as the fighting between the rebels and the army continued.

Two land mine explosions in Trincomalee killed one security official and wounded two police officers.

Also, at least two soldiers were wounded when Tamil forces attacked army front-line positions in the northern Jaffna peninsula with mortar shells and small arms fire.  An army spokesman says the military counter-attacked.  There were no immediate reports of rebel casualties.
