Police say a university professor in northwestern Bangladesh has been hacked to death on his way to work in an attack similar to other killings by suspected Muslim militants.

Police say A.F.M. Rezaul Karim Siddique was attacked Saturday on his way to the state-run university in Rajshahi city, where he taught English.

Deputy police commissioner Nahidul Islam says the attack is similar to recent killings of atheist bloggers in Muslim-majority Bangladesh by radical Islamists.

No groups have claimed responsibility for the attack and police are investigating.
