A group of Rohingya refugees is adrift in a boat in the Andaman Sea without food or water, the United Nations said Wednesday, as their families worried that many may have already died, according to an AP report.

The U.N. High Commissioner for Refugees, or UNHCR, said it understands that some of the refugees died after the boat left southern Bangladesh about two weeks ago. It said it does not know the boat's exact current location.

Reports said about 90 refugees, including some children, started the journey to seek better lives. Human traffickers often lure refugees, promising them work in Southeast Asian nations.
