Four alleged members of the Revolutionary People's Liberation Party-Front (DHKP-C) terrorist group have been detained in Istanbul dawn raids, police said early Friday.

The anti-terrorism division of the Istanbul Police Department carried out raids after receiving notice that a senior member of the group was preparing for a major attack in the city. 

At least four people, including a senior operative identified as Huseyin K., were apprehended during the operations, according to police. 

The police also seized 4 guns, 8 cartridge clips, over 1,000 bullets, as well as some organizational documents.

On Thursday, two Turkish police officers were injured in a gun and grenade attack in the city’s Bayrampasa district, Istanbul’s governor said.

Two female assailants said to be involved in the incident were later "neutralized" in a follow-up operation, said Governor Vasip Sahin.

Istanbul police identified the two dead assailants as Cigdem Yaksi and Berna Yilmaz, both members of the terrorist DHKP-C.

The DHKP-C is also listed as a terrorist organization by the U.S. and EU.

The group has carried out a number of attacks in Turkey, including a suicide bombing on the U.S. embassy in Ankara and an attack targeting the U.S. Consulate General in Istanbul.
