COX’S BAZAR, Bangladesh (Reuters) - Bangladesh police killed three people suspected of trying to smuggle 15 Rohingya Muslim refugees to Malaysia in a clash on Tuesday near the South Asian nation’s main refugee camp, an official said, the second such incident in as many months.

Nearly 900,000 Rohingya who fled a military-led crackdown in neighboring Buddhist-dominated Myanmar in 2017 live in Kutupalong, the world’s largest refugee camp, and other temporary settlements in Bangladesh’s beach town of Cox’s Bazar.

“On sensing the presence of our team, they fired on police, and police also responded,” said Prodip Kumar Das, a police official in the nearby town of Teknaf.

The men attempting to smuggle the refugees, who included some girls, were shot and died on the way to hospital, Das added. The refugees were rescued and sent to two different camps after initial questioning.

The clash, around 30 km (19 miles) from Kutupalong, followed a tip-off to police, Das told Reuters, adding that they had retrieved three locally-made guns and 15 rounds of ammunition.

The men were themselves Rohingya known to be human traffickers living in the area since their arrival in Bangladesh before 2017, he added.

Rohingya civilians who left Myanmar have said they faced atrocities at the hands of its armed forces but almost all such accusations have been denied by the authorities.

With doubts over whether they will ever return to Myanmar, some refugees in Bangladesh are being drawn toward drugs and violence, say people in the area and aid workers.

The risks of being trafficked have increased as refugees are lured by the promise of work. Anti-trafficking groups fear that routes through the Bay of Bengal are being used to smuggle out Rohingya refugees.

In recent months, police and the coast guard have rescued several dozens of them. Last month police killed two suspected smugglers in a gun fight in a nearby area.
