(QHA) -

Deadly fighting in eastern Ukraine must end this week, Ukraine's new President Petro Poroshenko has pledged.

"For me, every day that people die, every day that Ukraine pays such a high price is unacceptable."

He stressed that it was vital to "restore the Ukrainian border so that the safety of each Ukrainian citizen is guaranteed".

The president's comments came after the meeting with the special envoy from the Organization for Security and Co-operation in Europe (OSCE), Heidi Tagliavini, and the Russian ambassador to Kiev, Mikhail Zurabov.

Poroshenko also suggested to hold daily meetings of the so-called trilateral "contact group" to try to achieve a peaceful settlement in the eastern Donetsk and Luhansk regions.

Meanwhile, fighting has continued in and around the rebel-held city of Sloviansk.

Kiev and the West accuse Russia of supporting separatists in the east - a claim denied by Moscow.
