These measures will be stipulated in an additional protocol to the Council of Europe Convention on the Prevention of Terrorism, according to the source.
"In light of the terrorist attacks in Paris [Council’s leadership] has suggested to enhance countering terrorism actions and, if necessary, to develop new ones," the source said.
In late February, representatives from 47 member states held a session in Strasbourg to discuss a range of counterterrorism measures. The meeting came in the wake of three days of gun attacks in Paris, in which 17 people were killed.
The source explained that, in particular, the organization has pledged to ensure the signing and ratification of the European Convention on the Prevention of Terrorism by all its members and finalizing the additional protocol to the Convention.
The protocol is intended to introduce criminal liability for deliberate attempts to recruit for terrorist attacks, for organizing terrorist training and travelling to the territory of another state to carry out a terrorist act.
The Council of Europe Convention on the Prevention of Terrorism is a regional multilateral treaty created in Warsaw on May 16, 2005. Most notable among its provisions are three new offenses: public provocation to commit a terrorist offense, solicitation of persons to commit terrorist offenses, and participating in training for terrorist offenses.
Participants to the convention are required to establish these offenses in their national legal systems. So far the convention has been ratified by 32 states out of 47 members.
Signing of this additional protocol comes in the wake of the continued appeal of the Islamic State (IS) jihadist group and their active recruitment around the globe, including many citizens of the European countries. According to a UN estimate, more than 15,000 foreign fighters have traveled to Syria to join various extremist groups since 2011.
