NEW DELHI - A powerful 7.2-magnitude earthquake hit India's southern Nicobar Islands on Sunday, triggering panic in the islands and prompting Thailand to issue a tsunami warning for the region devastated by December's earthquake and tsunami.

There were no immediate reports of casualties or damages. The islands are in the Indian Ocean between India and Thailand, where some 5,400 people died in the Dec. 26 Indian Ocean tsunami. By late Sunday, no tsunami was seen and Thailand withdrew its warning.

Sunday's quake also was felt in Indonesia's Aceh province, the area hit hardest in December tragedy.

Aceh residents, jolted from their sleep, said the quake rattled their homes for about 10 seconds. Some went outside to look for damage, returning minutes later when none was found.
