Ukrainian President Petro Poroshenko has warned that, if a bilateral ceasefire does not take effect at midnight on Sunday, February 15, Kyiv will demand that an extraordinary meeting of the European Council be convened.

Meeting with Hungarian Prime Minister Viktor Orban on Friday, Poroshenko informed him of the outcomes of the Thursday meeting of the Normandy Quartet leaders in Minsk and a European Council meeting in Brussels, stressing the importance of a ceasefire agreement, the Ukrainian presidential press service reported.

Talking about a rocket attack on Artemivsk, in which three locals were killed, including a 7-year-old child, and the shelling of the community of Hirnyk from Russian-made rocket launchers on February 13, Poroshenko said: "Considering what we achieved in Minsk, this is not only an attack on Ukrainian civilians but also an attack on the Minsk results."

"If there is no mutual ceasefire at midnight on Sunday, we will insist on calling an extraordinary meeting of the European Council, because Angela Merkel and Francois Hollande represent not only Germany and France [in negotiations on the Ukraine crisis] but also have a mandate from all of the EU," he said.

Poroshenko said he counted on Hungary's support, to which Orban replied that he understood the importance of a ceasefire and the observance of the Minsk agreements.
