Three people have been killed in two separate bomb attacks on beer gardens in Nigeria amid actions by a radical Islamist sect.

An explosive device went off at a drinking spot in a busy neighbourhood in the central city of Jalingo on Thursday night, killing two, Taraba State police spokesman Amos Olaoye said.

On Friday night, another bomb exploded, killing a woman and wounding her children, an emergency management official said.

Authorities said the attacks were under investigation.

A radical Islamist sect known as Boko Haram had struck bars in Nigeria’s north as part of its campaign to have strict Islamic law implemented across this nation largely split between a Christian south and a Muslim north.
