By Monday morning, the National Disaster Mitigation Agency (BNPB) had recorded 281 dead, 1,016 injured and 57 missing. Many of those killed were tourists, thought to be visiting the popular beach resort area over the long weekend before the Christmas holiday. The tsunami has damaged at least 611 homes, 69 hotels and villas, 60 shops and 420 boats.

BNPB spokesperson Sutopo Purwo Nugroho said that many victims were trapped under collapsed buildings, and that heavy machinery would be required to help with search and rescue efforts.

"Heavy machinery has not been deployed to all of the affected areas, especially Pandeglang [in Banten] and South Lampung [in Lampung]," he said, adding that more heavy machinery would be sent to the areas on Monday morning.

Among the fatal victims are Dinda Esta Juzar and Adel Hidayat, the wife and son of former The Jakarta Post photographer Arief Hidayat. (evi)
