Indonesia has allowed international humanitarian organizations to assist Tamil migrants stranded in Aceh after bad weather foiled the province's much-criticized plans to tow the group's boat back into international waters.

The boat came ashore more than a week ago after its engine broke down. Indonesia refused to let the 44 migrants disembark until Saturday.

They are now sheltered in tents, and Indonesian efforts to refloat the beached vessel have ended with it tilted on its side and its engine inundated by seawater.

The International Organization for Migration said Tuesday that Indonesia has invited it and the U.N.'s refugee agency to assist the migrants.

IOM said it assessing what the migrants' needs are likely to be in the coming days and weeks.
