AKIPRESS.COM - The leaders of France and Germany Saturday voiced "extreme concern" over the ongoing violence in Ukraine and called for a ceasefire after 49 died when pro-Russian insurgents shot down an army plane, Focus reported.

During a telephone call with Russian President Vladimir Putin, French President Francois Hollande and German Chancellor Angela Merkel "stressed the importance of rapidly reaching a ceasefire in Ukraine," according to a statement issued by Hollande's office.

"It is about creating the conditions to de-escalate the situation on the ground, especially by preventing the transfer of fighters and weapons across the border (with Russia) and calling on the separatists to end their fighting," the statement added.

Fighting between pro-Russian rebels and Ukrainian army troops has raged for weeks in the country's east and Saturday's plane crash was the single most deadly incident in more than two months of clashes.
