Political leaders have condemned dissident republicans believed to be responsible for a car bomb attack on a Northern Ireland police station.
There were no initial reports of injuries after a taxi driver was forced at gunpoint to drive the device to Londonderry's Strand Road police station.
But after widespread damage was caused by the bomb, the area's MP, Mark Durkan, condemned those behind the attack.
The SDLP politician said: "This was a cowardly, dangerous and vulgar act. It is extremely fortunate that no injury has been caused or life lost as a result of this attack.
"Those responsible for this incident have achieved nothing and this campaign of violence will achieve nothing."
Police said two men, one armed with a gun, hijacked the taxi driver shortly before 3am. The bomb was loaded into his car and he was forced to drive to the police station.
Officers are understood to have been evacuating the area when the device exploded.
Damage was caused to the heavily fortified station, plus surrounding buildings including a nursing home and apartments.
The attack comes weeks after Londonderry was boosted by the positive response to the Saville Inquiry report into the events of Bloody Sunday, and after it was named UK City of Culture.
Mayor Colm Eastwood said the people of the city would be outraged by the attack.
