At least three people, including a policeman, were killed and scores wounded in two separate bomb blasts on Saturday near a militant hideout that was raided by commandos in northeastern Bangladesh, police said.

The explosions in the Sylhet district came a day after a suicide bomber blew himself up at a security checkpoint near the country’s main airport in an attack claimed by Islamic State.

Two people were killed and more than 30 injured in one of the blasts near the hideout and a policemen died in the second in front of the building, police official Rokon Uddin said.

Several army and police personnel were among the injured, he added.
