Ukraine have agreed to begin to pull back heavy weapons, Russian general involved in implementing a truce says

Rebels in eastern Ukraine have agreed to begin to pull back heavy weapons from the frontline, a Russian general involved in implementing a truce says.

Gen Alexander Lentsov said the pro-Russian rebels had signed the orders to complete the withdrawal over the next two weeks, starting from Sunday.

It is not clear whether the move will be reciprocated by Ukraine.

This comes as Ukraine and the separatists exchanged 191 prisoners, a key part of the Minsk ceasefire deal.

It was the first step carried out successfully under the terms of the 12 February agreements signed in the Belarusian capital, brokered by France and Germany.

The exchange came as US Secretary of State John Kerry said Washington was considering "serious sanctions" against Russia following breaches of the truce, and that a decision would be made in the coming days.

But Kremlin spokesman Dmitry Peskov said sanctions would not help solve Ukraine's crisis.

Meanwhile, thousands of Ukrainians - as well as a number of European leaders - are expected to take part in a "dignity march" in the capital Kiev on Sunday, remembering the victims of sniper fire during protests last February.

Nearly 5,700 people have died since the fighting erupted last April Ukraine's eastern Donetsk and Luhansk regions, according to the UN.

This followed Russia's annexation of Ukraine's southern Crimea peninsula.

Multiple breaches

Gen Lentsov, a Russian member of the Joint Centre for Control and Co-operation (JCCC), said: "We have designated 22 February as "D-Day" as determined by the agreement from all sides. So from tomorrow [Sunday] we will within the period of 14 days observe the agreement on the pullback of heavy weapons." source bbc
