A Bangladeshi island regularly submerged by monsoon rains is ready to house 100,000 Rohingya refugees, but no date has been announced to relocate people from the crowded and squalid camps where they have lived for years, officials said.

Flood protection embankments, houses, hospitals and mosques have been built on Bhasan Char, or floating island, in the Bay of Bengal, officials said.

“Bhasan Char is ready for habitation.

“Everything has been put in place,” Bangladesh refugee, relief and repatriation commissioner Mahbub Alam Talukder said.

The island is built to accommodate 100,000 people, just a fraction of the million Rohingya Muslims who have fled waves of violent persecution in their native Burma.

About 700,000 people came after August 2017, when the military in Buddhist-majority Burma began a harsh crackdown against Rohingya in response to an attack by insurgents.

Global rights groups and the UN called the campaign ethnic cleansing involving rapes, killings and torching of thousands of homes.

Foreign media have not been permitted to visit the island.

Saleh Noman, a Bangladeshi freelance journalist who recently visited, described a community emerging there.

“I saw a market with about 10 grocery shops and roadside tea stalls.

“Some were selling fish and vegetables,” he said.

“All is set there with a solar power system and water supply lines.”

Bangladesh is a low-lying delta nation.

The island, 21 miles from the mainland, surfaced only 20 years ago and was never inhabited.

The Bangladesh navy has been implementing a multi-million-dollar plan to bolster the swampy island, which is submerged for months during annual monsoon season.

International aid agencies and the United Nations have vehemently opposed the relocation plan since it was first proposed in 2015, expressing fear that a big storm could overwhelm the island and endanger thousands of lives.

Mostofa Mohamamd Sazzad Hossain, a spokesman for the UN High Commissioner for Refugees in Bangladesh, said the agency is not ready to endorse the relocation and is waiting for a chance to visit the island after a November trip was cancelled.

“The UN has emphasised the importance of undertaking independent and thorough technical and protection assessments that consider safety, sustainability, and protection issues prior to any relocation taking into place.

“The assessment process should include onsite visits to Bhasan Char,” Mr Hossain said.

The current refugee camps near the beach town of Cox’s Bazar are overcrowded and unhygienic.

Disease and organised crime are rampant.

Education is limited and refugees are not allowed to work.

Still, most Rohingya are unwilling to return to Burma due to safety concerns.

Government officials did not have an estimate of how many refugees would be willing to be relocated to the island.

On Thursday, two Bangladeshi contractors involved with development of the island described construction there.

“We have built quality infrastructure.

“Bangladeshi villages have never seen such good work. This is like a modern township project,” one contractor said.

“We have built multi-family concrete homes, hospitals, mosques, schools, playgrounds and roads.

“There are solar-power facilities, a water supply system.

“We constructed raised concrete buildings that could be used as cyclone shelters.

“Many trees have been planted,” he said.

Bangladesh prime minister Sheikh Hasina has repeatedly told the UN and other international partners that her administration will consult them before making a final decision on the relocation, and that no refugees will be forced to move.

Bangladesh attempted to start sending refugees back to Burma under a bilateral framework last November, but no one was willing to go.

The Rohingya are not recognised as citizens in Burma, rendering them stateless, and face other forms of state-sanctioned discrimination.

A UN-sponsored investigation in 2018 recommended the prosecution of Burma’s top military commanders on charges of genocide, war crimes and crimes against humanity for the violence perpetrated against the Rohingya.

Burma is defending itself in the International Court of Justice in The Hague, Netherlands, after the West African nation of Gambia brought a case backed by the Organisation for Islamic Cooperation, Canada and the Netherlands.

Gambia in its submission said there was a “serious and imminent risk of genocide recurring” and called for emergency measures to prevent Burma from committing any further atrocities or erasing any evidence.

The court is expected to deliver a decision on January 23 on what measures should be imposed.

Kamal Hossain, Bangladesh’s top government official in Cox’s Bazar, said that discussions attempting to convince refugee families to move to the island are continuing.

“We are ready. This is a continuous process,” he said.
