Bangladesh on Tuesday moved a second group of Rohingyas, a Muslim minority, from overcrowded refugee camps to new homes on a remote island.

Human rights organizations are still very concerned about the new location, as it would be very vulnerable to storms.

The navy brought 1,804 Rohingyas to the island of Bhasan Char on Tuesday with five ships.

The first group of 1,642 people was moved in early December.

Bhasan Char is seen by the government as a solution to the overcrowded refugee camps near the border with Myanmar.

More than a million Rohingyas live in the camps.

They fled Myanmar because of violence against the ethnic minority.

On Bhasan Char, facilities have been built for about 100,000 refugees, according to authorities.

For example, a dike has been built next to houses to prevent flooding.

Aid organizations are concerned about the location, as the island in the Bay of Bengal is prone to flooding.

However, according to the authorities, the island is "completely safe".

Allegations from Rohingya community

The move is voluntary, according to the government, but several refugees from the first group say they have been forced.

Amnesty International questions the relocations due to allegations from the Rohingya community and a lack of transparency.

The United Nations says it was not involved in the relocation of the Rohingyas, but calls on the government to ensure that no refugee is forced to move to Bhasan Char Island.
