The measure, which must be formally approved by parliament, requires stepped-up document and vehicle checks, among other measures, the council's secretary Oleksiy Danilov said.

Danilov said he would deliver a report to Ukraine's parliament later on Wednesday, with lawmakers expected to approve the added security measures this week.
