At least six people have been killed and more than 200 injured in two separate car bombing attacks in Turkey.

The first attack targeted at a police station in the eastern city of Van.

BBC reports that two civilians and a police officer were killed in the attack, with 73 others injured.

The second bombing came several hours later when a police station in the city of Elazig was attacked.

Three officers were killed and more than 140 people injured.

The outlawed militant group the PKK are believed to be behind the attacks, officials have said.
