A formal decision over a six-month extension of the sanctions approved on Wednesday by the Committee of Permanent Representatives (COREPER), concerning the freezing of the bank accounts and EU travel bans for Russians and eastern Ukrainian representatives, will be made by the Council of the European Union by September 15, after the necessary documentation is prepared, a European diplomatic source told Interfax.

Currently, the list includes 150 individuals and 37 companies, he said.

At this stage it is not possible to confirm the final figures that will be revealed after the restrictive measures are extended, i.e. after the formal decision is made, the source said.

He recalled that COREPER on Wednesday agreed to extend the sanctions list involving individual measures expiring on September 15, until March 15, 2016.

These restrictive measures extend to the individuals and organizations whom the EU considers to have been involved in the actions against Ukraine's sovereignty, territorial integrity, unity and independence, the source said.
