A car bomb attack has killed at least 19 people and injured 60 more in the Nigerian capital Abuja, officials say.

The explosion happened in the suburb of Nyanya, close to a motor park where at least 70 people died in a bomb blast on 14 April.

Witnesses said the explosion targeted a police checkpoint near a bus station.

No group has claimed responsibility for Thursday's attack. The Islamist militant group Boko Haram said it was behind the fatal explosion last month.
