Security forces have detained 1,050 suspects across 34 Turkish provinces since the nationwide "anti-terrorist operations" in the country began, official sources said Monday.

Most of the suspects allegedly belonged to Daesh, Kurdistan Workers’ Party (PKK) and the far-left Revolutionary People's Liberation Party-Front (DHKP-C), the Turkish Prime Minister’s Office of Public Diplomacy said in a statement Monday.

The statement also said that under Article 4 of the NATO treaty, ambassadors of all 28 NATO allies would meet in Brussels on Tuesday following Ankara’s request amid Turkey’s operations against the outlawed organizations.

Turkey will continue to fight against the terrorist threats from outside and inside, the statement added.

Earlier, Turkish security forces said that at least 256 suspects were detained in nationwide operations on Monday.

Police said that 15 people suspected of links with Daesh were arrested in raids in Ankara province on Monday morning.

In the eastern province of Erzurum, 34 people were detained during an anti-PKK operation.

In the southeastern provinces of Diyarbakir and Mardin, security forces detained 135 people in another anti-PKK operation. Pistols, shotguns, explosives devices, Molotov cocktails and fireworks were also seized, the Provincial Security Directorate of Diyarbakir said.

An unlicensed pistol, three licensed shotguns, blank firing guns, four magazines, 104 cartridges, two balaclavas, nine mobile phones, 10 computers, nine mobile phone SIM cards and documents belonging to the organization were also seized in the operation.

The nationwide operations are the latest in a recent wave of arrests that have seen hundreds of suspected Daesh, PKK and DHKP-C supporters arrested across Turkey.

Turkey recently launched airstrikes against Daesh and the PKK in Syria and Iraq. On Friday night and in the early hours of Saturday, Turkish jets bombed PKK camps in northern Iraq for the first time in the last two-and-a-half years. Turkey also launched attacks against Daesh. Turkish jets again hit PKK targets inside and outside Turkey on Sunday night.
