Bomb causes 'substantial damage'
A car bomb has exploded in Northern Ireland, police said.
The device, planted in a Vauxhall Corsa, detonated just after midnight outside a bank at the back of the Da Vinci retail complex near the University of Ulster in Londonderry.
A spokesman for the Police Service of Northern Ireland said: "A warning had been received just an hour earlier and a cordon was in place.
"Initial inquiries suggest there were no injuries. Substantial damage was caused to the retail complex and to the car."
Dozens of homes and businesses, including a nursing home, were evacuated.
Motorists are being warned there will be severe traffic congestion in the area later in the morning.
