DHAKA, 31 May, 2021, (TON): Hundred and thousands of Rohingya’s on Monday staged "unruly" protests against the conditions of cyclone-prone island off Bangladesh where they were moved from vast camps on the mainland, said police.

Starting from December, 18,000 Rohingya shifted out of a planned 100,000 refugees to the low-lying silt island of Bhashan Char from the Cox's Bazar region, where some 850,000 people live in squalid and cramped conditions.

Most of them had fled a brutal military offensive in neighbouring Myanmar in 2017 that UN investigators concluded was executed with "genocidal intent".

About 4,000 people were involved in Monday's protest, police said, and coincided with an inspection visit by officials from the United Nations refugee agency (UNHCR).

"The Rohingya who are there became unruly the moment the UNHCR representatives landed (on the island) by helicopter today," local police chief Alamgir Hossain told AFP news agency.

"They broke the glass on warehouses by throwing rocks. They came at the police... Their demand is they don't want to live here."

After the first transfer on December 4 to the flood-prone island in the Bay of Bengal, several Rohingya says that they were beaten and intimidated into agreeing to be relocated.

However, Bangladesh government has rejected the allegations, saying the island was safe and its facilities far better than those in the Cox's Bazar camps.

Bangladesh has transferred Rohingya refugees to a remote island, despite opposition from international aid agencies. The island, named "Bhasan Char" or floating island, first emerged just 20 years ago as a sandbar in the Bay of Bengal.

About 750,000 Rohingya Muslims had to flee from Myanmar to neighboring Bangladesh in 2017 after Myanmar's military launched a counterinsurgency operation, involving mass rape, murders and the torching of villages.
