One assailant, a woman, was captured later at a building nearby and taken to a hospital. Turkey’s state run news agency said the woman was identified as part of a leftist group that the Turkish government banned.
The governor’s office in Istanbul said the police were searching for another woman who was involved in the consulate attack.
The woman who was captured was identified as Hatice Asik who is 42 and said she was a member of the Revolutionary People’s Liberation Army-Front a far left group or the DHKP-C.
The organization claimed responsibility for a suicide attack in 2013 on the U.S. Embassy in the capital of Ankara that killed a security guard who was Turkish.
In Monday’s attack, no injuries were reported.
Only hours earlier, a bomb attack overnight at a local police station injured three Istanbul police officers as well as seven civilians.
Police said a car bomb had been exploded by the assailants near the police station. The unknown assailants later fired upon police inspecting the bomb explosion, sparking a second gunfight with the police that killed a police inspection team member and two of the assailants.
No claims of responsibility were known in the police station attack and authorities did not know if it was connected to the assault on the consulate.
Kurdish rebels on Monday in Sirnak a southern province in the country, fired on a helicopter that had been carrying conscripts, who had finished their term of duty or were taking leave. The attack killed one and injured another, said the military.
The rebel group of Kurds and the left wing DHKP-C both have origins that are Marxist and have worked together previously.
These attacks come during a period of increased violence between security forces in Turkey and rebels of the PKK or Kurdistan Workers Party. Turkey has also taken a more active role against the radical militant group Islamic State.
