KIEV (Reuters) - Ukrainian President Petro Poroshenko spoke to U.S. Vice President Joe Biden on the telephone on Thursday, saying he was ready to engage in a ceasefire with pro-Russian rebels if certain conditions were met, his office said.
"Poroshenko emphasized he was ready to return to a ceasefire as soon as confirmation was received that it is being fulfilled in a bilateral format as well as the release of hostages and the establishment of control over the border through OSCE monitoring," a statement on his website said.
