Bangladesh’s brick factories and other factories employing thousands of people have fired dozens of bombs in a wave of attacks against Bangladesher workers and businesses, the government says.

The blasts were the latest in a string of violence that has killed hundreds and displaced millions in Bangladesh since the July 1 elections.

Prime Minister Sheikh Hasina announced on Friday that the government was cracking down on the perpetrators.

“We have taken many steps to curb the proliferation of violence in our country,” she said in a statement.

“We have strengthened the security forces, we have also taken steps to bring the perpetrators to justice.”

Bangladeshi Prime Minister Sheikh Hassanal Bolkiah said he would step up security measures.

Bangladesh has been grappling with a long-running political crisis, which has pitted the ruling Awami League, or Bangladesh Nationalist Party, against a military government led by the Bangladesh Nationalistic Party, or BNP.

The BNP has ruled the country for nearly a quarter-century.

The government says more than a million people have been displaced since the election.
