Bangladeshi police arrested six more suspects in their hunt for those responsible for last month's near-simultaneous explosions of hundreds of small bombs nationwide that left two people dead and about 125 injured, officials said.
The six men, including a head teacher at an Islamic seminary, were detained late on Sunday, police officials said on condition of anonymity.
On Aug. 17, more than 430 small homemade bombs went off at about the same time across the country.
Nobody has claimed responsibility for the explosions, but leaflets from the banned Islamic militant group Jumatul Mujahiden Bangladesh were found at all the blast sites, the government says.
Authorities have detained and interrogated more than 300 people suspected to be involved in the violence.
Most of those detained allegedly belong to the banned group, which is seeking to establish harsh Islamic rule in Bangladesh, a Muslim-majority nation governed by secular laws.
No one has been formally charged.
The six men arrested over the weekend were due in court yesterday, the officials said.
They said four men were arrested in Lakshmipur district, 95km east-southeast of the capital, Dhaka.
One was picked up in Manikganj district, 40km northwest of Dhaka, while the sixth was arrested in neighboring Tangail district, the officials said.
