Nigeria has imposed curfews on nightclubs, bars, movies theatres and parks in the capital, Abuja, following several deadly bombing attacks.

The Federal Capital Territory Administration has ordered parks and gardens to close by 6 pm while nightclubs, bars, and movie theatres are allowed to stay open until 10 pm daily.

The agency says the curfew is necessary to ensure the safety of people and property following bombings blamed on the radical Boko Haram Islamic group.

On Sunday, suspected Boko Haram members threw a bomb into a beer garden in northeastern Nigeria, killing 25 people and wounding at least 12 others.

Earlier this month, Boko Haram claimed responsibility for a suicide bombing outside Nigeria's national police headquarters in Abuja that killed several police officers.

Boko Haram is pushing to impose strict Islamic law across the north. It launched a brief uprising against the government in July 2009, sparking a heavy military response and a week of fighting that killed 700 people.
