Four policemen were wounded after some men attacked them with explosives at a security checkpoint in Bauchi State, Nigeria. Police spokesman for the northern state, Mohammad Barau said on Monday that two men on motorcycle threw a parcel containing explosives at a police checkpoint in the city of Bauchi.
According to him, the police have not suspected anyone. However, similar motorcycle-mounted attacks targeting security officers have been blamed on a radical Muslim sect locally known as Boko Haram in the city of Maiduguri, some 280 miles (450 kilometers) away.
The group has claimed responsibility – in unverified statements, for multiple blasts that hit Bauchi in May, another city and a town near the capital, killing 18 people.
Boko Haram seeks the strict implementation of Shariah law in northern Nigeria.
