From our news desk. More fighting in Donetsk:
Reports from eastern Ukraine say some 10 people have been killed in shelling in the rebel-held city of Donetsk.
Three people were reportedly killed when a shell exploded in a school playground on October 1.
Several others reportedly died when a shell hit a mini-van in a nearby street.
The blasts occurred as pupils returned to school, after the start of the school year was postponed from September 1 due to fighting between Ukrainian government forces and pro-Russian separatists.
Shelling has repeatedly been reported in Donetsk despite an September 5 cease-fire in the conflict, which has killed more than 3,000 people since April.
The Donetsk airport has been a focus of fighting since the cease-fire.
A rebel commander told the AP news agency on October 1 that the rebels controlled most of the airport.
And now this:
The head of the European Commission says an EU-Ukraine trade deal can only be changed by Brussels and Kyiv – not Moscow.
Jose Manuel Barroso made the remarks in a letter to Russian President Vladimir Putin released on October 1.
Ukraine's parliament ratified its agreement with the EU last month.
However, the implementation of the trade part of the deal has been delayed until January 2016 to appease Russia, which says the pact will hurt its markets.
Moscow has called for more three-way negotiations to amend the deal and threatened to curtail Ukraine's access to Russian markets if Kyiv implements it.
In his letter, Barroso warned Putin not to impose new trade measures, saying it would threaten the agreement with Russia to delay the EU-Ukraine pact.
