Ukraine's army said on Wednesday that a new nine-day truce with insurgents was holding despite small skirmishes that claimed the lives of two government soldiers this week.

"A relative calm on the front is holding," Ukrainian military spokesman Andriy Lysenko told reporters. "On average, the rebels violate the cease-fire 10 times a day, but they no longer use heavy weapons."

Lysenko said the insurgents staged a raid in the eastern separatist province of Lugansk that was repelled in a 30-minute gun battle in which one government soldier was killed. Another Ukrainian serviceman was reported killed on Tuesday. The militia command reported no casualties from the mostly Russian-speaking industrial war zone.

The bitter foes agreed on September 1 to more strictly respect an often-broken February armistice that was meant to end fighting quickly and settle all political disputes by the end of the year.

But a new round of talks in the Belarussian capital Minsk on Tuesday made no reported progress toward a deal that would see both armies withdraw their smaller weapons from the 500-kilometer demilitarization zone.

Rebel command said it expected a special security task force representing the warring sides and Russia to continue with the negotiations with the help of European mediation on Wednesday.

The UN estimated on Tuesday that the 17-month conflict on the European Union's eastern frontier has claimed the lives of nearly 8,000 people and injured almost 18,000 - most of them civilians.
