BRUSSELS, June 27. /ITAR-TASS/. The European Union's summit held in Brussels Friday demanded that hostages be released, border checkpoints vacated and talks in the East of Ukraine started by June 30, Ukrainian President Petro Poroshenko told journalists in Brussels on Friday.

“The EU summit demanded that the following measures be taken by Monday, June 30: the return [to the government forces] the border crossing points of Izvarino, Krasny Partizan, Dovzhansky, the release of all hostages, including Organization for Security and Cooperation in Europe representatives, and the start of full-fledged talks on the peace plan,” Poroshenko said.

Should this not happen, he said, the European Council is ready to “gather at any moment again to discuss new restrictive measures against the Russian Federation”.

Poroshenko on Friday pledged to make a decision on ceasefire extension by 72 hours in Ukraine’s embattled Southeast later in the day upon return from Brussels.

“I need to return and hold consultations with the military and government. The ceasefire will be in force until evening, and the decision will be made by that time,” Poroshenko said.

Poroshenko, who won the May 25 early presidential election in Ukraine and took office on June 7, on June 20 announced a ceasefire in Ukraine’s Southeast until June 27. He also presented a peace plan to settle the situation in the Southeast during his first working trip to the Donetsk Region.

Militias in the Southeast agreed to the truce despite numerous reports that the ceasefire had been violated.

Kiev’s punitive operation against federalization supporters in Ukraine’s Southeast involving armored vehicles, heavy artillery and attack aviation has killed hundreds of people, including civilians, left buildings destroyed and damaged and forced tens of thousands to cross the border from Ukraine to Russia.
