Ukrainian President Petro Poroshenko has signed changes to the counterterrorism laws, giving broader powers to counterterrorist agencies, Interfax reports.

"These changes must resolve the problem of fully restoring law and order and the proper functioning of government agencies, guaranteeing public safety and health, and discontinuing the activities of illegal armed groups and terrorists," the president's website said on Wednesday.

The changes were passed by Ukrainian Parliament on June 5. The new law extends the list of counterterrorist agencies by adding, in particular, the Ukrainian State Service for Special Communications and Information Protection.

The new law gives powers to the Defense Ministry to ensure protection against terrorist encroachments on the assets and property of the Ukrainian Armed Forces, weapons of mass destruction, rockets and small-arms weapons, ammunition, explosive and toxic substances held at military bases or in certain locations in the event of being used in an anti-terrorist operation.
