Six people have been killed and more than two hundred injured in two separate car bombs targeting police stations in eastern Turkey amid a surge in attacks linked to Kurdish militants.

A car bomb exploded on Thursday morning outside the police headquarters of the eastern city of Elazig, killing three police officers and wounding at least 217 people.

Late on Wednesday, another car bomb at a police station in the southeastern city of Van left two civilians and one police officer dead. At least 73 others, including 53 civilians, were injured.

The Van bombing was captured on video by guests attending a wedding at a venue close to the police station.

The groom and bride are seen dancing the halay, a traditional line dance, when an explosion shatters the windows behind them, sending the wedding party running and screaming in panic.
