Moscow (CNN)German Chancellor Angela Merkel and French President Francois Hollande met Friday with their Russian counterpart and began to draw up a new proposal to end the bitter conflict in eastern Ukraine. The peace talks with President Vladimir Putin ended early Saturday, the Kremlin told CNN. Putin's press secretary, Dmitry Peskov, said a joint document based on a prior peace plan agreed to in Minsk, Belarus, in September, is not yet complete. The parties will engage in further talks by phone on Sunday, Peskov said. The new diplomatic push comes as a worsening conflict in eastern Ukraine is taking an increasingly heavy toll on civilians.
