Several people were killed in Turkey Monday after a series of attacks on police officers and soldiers. A bomb exploded at a police station in Istanbul. The explosion wounded at least 10 people, including three police officers.

Turkey’s state-operated news agency reported that Istanbul police are blaming the attack on “terrorists.” Later at the police station, officers exchanged gunfire with two attackers and killed them.

Also on Monday, a bomb exploded along a road in southern Turkey. Four police officers were killed.

In a separate incident, two gunmen shot at an American diplomatic office in Istanbul. Police fired back at them. No one was injured. The attackers fled, but police say they detained one of them, a woman.

Officials say she is a member of the Revolutionary People’s Liberation Party-Front. Turkey, the United States and the European Union consider the group a terrorist organization. Its supporters have carried out several attacks, including a suicide bombing two years ago at the U.S. embassy in Ankara.
