KIEV, Ukraine (AP) — Ukraine’s security agency on Sunday warned of a heightened risk of terrorism, including from nearly three months of anti-government protests. The warning raised the pressure on the opposition as parliament tries to find a way out of the crisis.

The Security Service of Ukraine said it was putting its counter-terrorism units on alert, after receiving a large number of bomb threats across the country at airports, train stations, pipelines and other locations. In what was seen as a warning to the opposition, the seizure of government buildings also would be viewed as manifestations of terrorism, the agency said in a statement.
