Authorities in the Indonesian province of Aceh turned back a boat with more than 40 Sri Lankan Tamil men, women and children out to sea yesterday after rescuing it last weekend.
It would be the second attempt in the past week to remove the vessel from Indonesian waters after it suffered engine trouble and was discovered stranded last Saturday.
The migrants have been at sea for about a month and were trying to reach the Australian territory of Christmas Island.
The province is refusing to let the migrants, which include nine children and a pregnant woman, land despite Indonesian Vice President asking Aceh officials to provide shelter.
On Thursday, six women tried to leave the boat as it sat in shallow waters but police fired warning shots.
