The court in Laxmipur district also sentenced five other militants to life in prison for their role in the bombings.
The defendants are members of the outlawed militant group Jumatul Mujahedin Bangladesh. The group wants to replace the country's secular legal system with strict Islamic laws.
Meanwhile, Bangladeshi police have detained four people in Dhaka following accusation by the opposition Awami League they were plotting to kill its leader Sheikh Hasina and her younger sister.
The Awami League says the assassination was to take place on Tuesday during ceremonies to mark the anniversary of Hasina father's assassination.
