Putin said on a trip to Vienna Tuesday that the seven-day cease-fire Ukrainian President Petro Poroshenko announced Friday wasn’t enough.

He added that the end of hostilities must be accompanied by talks.

Putin’s statement came as a Ukrainian government spokesman said that a military helicopter was shot down in Slovyansk.

Vladislav Seleznev, a spokesman for the Ukrainian operation against the insurgents in the east, was quoted by the Interfax news agency as saying that the Mi-8 helicopter was shot down over rebel-controlled area.
