Gunmen wounded at least seven people and killed 20 in an assault on a Rohingya refugee camp in Bangladesh on Friday, heightening tensions in the settlements after the recent shooting of a community leader.
The attackers randomly stabbed some victims and shot others with knives at the Balukhali refugee complex in Cox's Bazar near the border with Myanmar, a regional police chief said.
The killings came as tensions mount in the camps that house more than 900,000 refugees from Myanmar, after a Rohingya activist was shot dead outside his office three weeks ago.
Four people were instantly killed in the attack on Friday at the Darul Ulum Nadwatul Ulama al Islamia madrassa.
Three others died at a hospital in one of the camps that make up the Balukhali refugee complex.
Police did not say how many people were hurt but a medic with Doctors Without Borders MSF who requested anonymity said about 20 people were hurt.
About 20 seriously injured people came to our hospital, many with no arms, no legs or no eyes. Their condition is very bad. Three of them died, the doctor said.
Police official Kamran Hossain said Rohingya miscreants entered the madrassa before dawn and randomly hacked and shot people inside Security forces sent reinforcements to immediately seal off the camp, which houses more than 27,000 people. Camp residents shared images on social media of bodies on the floor of the madrassa.
We arrested one attacker immediately after the incident, said Shihab Kaisar Khan, regional chief of an armed police battalion, told reporters.
The man was found with a gun, six rounds of ammunition and a knife, he added.
Many Rohingya activists have gone into hiding or sought protection from the police and UN agencies since the killing of rights advocate Mohib Ullah by unknown assailants in a nearby Balukhali camp.
The 48 year-old teacher had become a leading moderate voice for the stateless community.
Some activists blamed the Arakan Rohingya Salvation Army ARSA for the killing.
ARSA is the militant group behind attacks on Bangladesh security forces in 2017 that set off a military clampdown and a mass exodus by 740,000 Rohingya into Myanmar. It has denied Ullah's killing in a Twitter statement and condemned any involvement.
Police say at least five people have been arrested for Ullah's murder. But activists say there is mounting fear of more violence in the camps.
Security was tightened after Ullah's death. In less than a month seven people have been killed. How can I trust the security system? said one refugee, Hakim, who asked to use only one name.
Human Rights Watch said in a statement this month that at least a dozen activists have approached the UNHCR refugee agency, the UNHCR, since the killing of Ullah.
Many said they had been threatened by militants.
UN High Commissioner for Human Rights called Ullah's death a clear example of the insecurity in the camp and apparent attempts to silence moderate civil society voices Other activists said the camp's narrow streets are taken over by militants and criminals after dark as police barely patrol at night.
They seem reluctant and intimidated. A serious tension lingers within the camps since Ullah's murder, Kyaw Min, leader of Ullah's Arakan Rohingya Society for Peace and Human Rights ARSPH told AFP in a recent interview.
Bangladesh police have insisted that full security is assured.
