At least six naval personnel were seriously wounded in explosions at the end of prayers on Friday at a mosque inside a Bangladesh naval base in Chittagong, police said.

Two people were arrested in connection with the blasts. Police said they had confessed to being members of banned militant group Jama’atul Mujahideen Bangladesh.

“Two bombs blasted at the mosque after Jumma prayer and six persons were critically injured,” said Devdas Bhattachariya, an additional commissioner of Chittagong Metropolitan Police, adding that all the wounded were from the navy. No one from the navy was available for comment.

Security forces also deactivated five unexploded bombs from the mosque in the port city of Chittagong.

Last month, a Shiite Muslim mosque in Bangladesh’s northern district of Bogra was attacked, killing a cleric and wounding three other people in the second attack on the tiny Shiite Muslim community in a month.

Daesh claimed responsibility for those attacks.

Daesh also claimed responsibility for the killings of a Japanese citizen and an Italian in the past months, but police blamed those killings on Jama’atul Mujahideen Bangladesh.
