Before Tuesday, the rebels had shot down at least two Ukrainian army helicopters and a plane
The Ukrainian military says one of its helicopters has been shot down by pro-Russian rebels in the east, killing all nine people on board.
It says the Mi-8 helicopter, used for transporting military cargo, was hit by a rocket shortly after take-off outside the rebel-held city of Sloviansk.
It comes a day after the rebels vowed to observe a ceasefire until Friday, in response to a government peace plan.
But Russia’s president warned that the week-long truce was not enough.
Vladimir Putin said it should be extended to try to hold “substantive talks” between the Ukrainian government and the separatists.
The rebels have not commented publicly on the Ukrainian military’s claims.
Before Tuesday, the rebels – who continue to hold towns in the regions of Donetsk and Luhansk – had shot down at least two Ukrainian army helicopters and a plane.
Earlier in the day, President Putin asked the Russian parliament to revoke the right of military intervention in Ukraine.

President Putin stressed that Moscow would continue to protect ethnic Russians in Ukraine

The move was aimed at “normalising the situation” in the eastern regions of Ukraine, Mr Putin’s press secretary said.
The parliament authorised Mr Putin to use force in Ukraine on 1 March.
Ukrainian President Petro Poroshenko said Mr Putin’s latest move was a “first practical step” towards settling the crisis in the east. It came after Russia had officially supported Ukraine’s peace plan, which included the week-long ceasefire.
But speaking later during a visit to Austria, Mr Putin stressed that revoking the right on using force did not mean that Russia would stop protecting “ethnic Russians in Ukraine… who consider themselves part of the broad Russian world”.
Since March, Moscow has annexed Ukraine’s southern Crimea peninsula – a move condemned by Ukraine and Western leaders.
The takeover achieved with the help of troops without insignia. Despite initial denials, Mr Putin later admitted that they were Russian armed forces.
However, Russia denies accusations by Ukraine that Russian troops are helping and arming the separatists in eastern Ukraine.
