A Christian pastor and his 14-year-old daughter have been abducted from a predominantly Muslim refugee camp in Bangladesh after families were viciously attacked and robbed by an angry mob.

Dozens of attackers beat up Christian residents, vandalized homes, and looted personal property in the sprawling Rohingya refugee camp in Cox's Bazaar, Human Rights Watch reported.

The pastor and his daughter were abducted the day after the attack and his wife claims the teenager has been forced to convert to Islam and marry.

More than 700,000 Rohingya Muslims live in the refugee camp after fleeing the Myanmar military's 2017 campaign of ethnic cleansing. Approximately 1,500 Rohingya Christians are among them.

The abducted pastor, named only as Taher, were abducted from their shelter in the camp on January 27.

His wife Roshida told Human Rights Watch that she fears her husband has been killed.

She added: 'No one can give me any clear information, but my relatives told me that my daughter has been forced to convert to Islam and marry.'

Police said that scores of men attacked 22 Christian families living in Kutupalong Camp 2 in Cox's Bazaar the night before the abductions.

At least 12 Rohingya Christian refugees were injured and hospitalized following the attack.

A makeshift Christian church and school were also smashed.

After the attack the families relocated to a United Nations transit centre and filed a police case against 59 alleged assailants.

The Benar News Agency and Radio Free Asia have reported that camp residents believe that the attackers are linked to the Arakan Rohingya Salvation Army (ARSA), an ethnic Rohingya armed group.

But an ARSA representative denied and condemned the attacks on Christians, saying the assailants were harming the group's fight for Rohingya rights.

Victims say the Bangladesh authorities, who described the attack as an 'ordinary law and order incident' and not an attack aimed at Christians, are not doing enough to protect them or to find Taher and his daughter.

Camp officials 'try to avoid our queries,' said one man.

Another said a police officer in Cox's Bazar told him that if the victims wanted to be safe they should 'go to the moon.'

Rohingya Christians have previously reported facing threats and violence in the camps.

The UN special rapporteur on human rights in Myanmar, Yanghee Lee, has expressed her concern for Rohingya Christian refugees who are facing 'hostility and violence.'

The Bangladesh authorities should urgently locate Taher and his daughter and bring those responsible to justice.

The government should also act immediately to protect all vulnerable groups in the country's refugee camps, including religious minorities like Rohingya Christians.
