Police in Turkey’s capital say they have detained four ISIL members suspected of preparing an attack during May 1 International Labor Day demonstrations.

Turkish security officials told an Anadolu Agency correspondent that the Ankara anti-terror department detained the four suspects at midnight on Saturday.

Saturday's arrests followed technical and physical surveillance and it is reported that the suspects are from Syria.

The anti-terror operations will continue, say police.

May 1 is celebrated by many labor unions and workers worldwide. May Day is generally a public holiday in many countries and is an official holiday in Turkey.
