In Indonesia , hundreds of people are still missing days after several remote islands were hit by a deadly tsunami. At least 343 people have died on the Mentawai Islands and almost 400 are unaccounted for, amid fears they were swept away by the wave. Poor weather is slowing rescue efforts but an aid ship carrying food, water and medical supplies has now arrived in the disaster zone. Indonesian President has visited survivors on the islands. Susilo Bambang Yudhoyono cut short a trip to Vietnam to oversee the rescue effort and headed in a helicopter loaded with food and other basic necessities to the remote and inaccessible area. The islands were inundated after a 7.7 magnitude undersea earthquake triggered the tsunami three days ago.
