The Red Cross says a hand grenade has exploded outside its offices in Sri Lanka's embattled northern Jaffna peninsula.

The blast caused "material damage" but no one was hurt.

The organisation has expressed concern about the attack, urging all sides in the Sri Lankan conflict to respect aid workers.

Jaffna has been virtually cut off from the rest of the island as a result of intensified fighting between Tamil Tiger rebels and government soldiers along their unofficial front lines.

The Liberation Tigers of Tamil Eelam (LTTE) rebels and the government have both told peace broker Norway they are prepared to meet for talks after a five-month deadlock to end fighting that has killed hundreds of civilians, troops and rebels since late July.

The latest fighting began over a key irrigation canal on the country's east coast and has left a truce signed in 2002 in tatters.

More than 60,000 people have been killed in Sri Lanka's drawn out Tamil separatist conflict.
