Aftershocks continued to rock the Andaman and Nicobar Islands on Tuesday where 3,000 people were killed and an equal number still missing after tsunami waves triggered by a massive undersea quake off Sumatra in Indonesia on Sunday hit the archipelago.

At least 3,000 people have been killed and another 3,000 are missing from all over the island.

Deputy inspector general of police, Andaman and Nicobar, A N Basudev Rao, told PTI that the island received a series of aftershocks since last midnight.

Residents rushed out of their dwellings to open areas at 12.45pm and again at 4am on Tuesday fearing a repeat of Sunday's catastrophe.

Sea water was also on the rise in Little Andaman even as relief and rescue operations were on in full swing in the affected areas, including the worst-hit Car Nicobar.

Quoting reports from Little Andaman, Rao said that 10,000 people have taken shelter atop a hill in the jungles in that
area.

Majority of the affected were from Car Nicobar and Nancowrie group of islands, he said. Full contact was yet to be established with the Nancowrie islands, he said.

Meanwhile, 152 tribals were rescued from Katchall in Nancowrie and taken to Camorta, while another 40 people were rescued in Kondul, he said.

The island administration was facing a major problem in disposing bodies as they had to be collected from jungles and other far flung areas, he added.
