ISTANBUL (AFP) - At least 18 people including two police officers were injured when a bomb went off near a concert venue in the southern Turkish city of Mersin, CNN-Turk news channel reported.

Three people were seriously wounded in the blast, the channel reported, adding that the concert, which had been attended by some 30,000 people, was drawing to an end at the moment of the explosion.

City mayor Macit Ozcan earlier told NTV television that around 10 people had been wounded in the blast, which he said was apparently caused by a bomb hidden under a police vehicle outside the venue.

Anatolia news agency reported that police had carried out a controlled explosion on a second suspect package discovered near the site.
