Ukrainian President Petro Poroshenko is offering a ceasefire if pro-Russian separatists in the east lay down weapons or leave Ukraine.  Poroshenko’s plan to try and end two months of fighting was announced today following his conversations with Russian and German leaders.

Meantime, U.N. monitors in Ukraine say they’re documenting a steady rise in killings, torture and abductions by armed groups in the country’s east.

The U.N. says at least 356 people, including 257 civilians, have been killed since May 7th. There have been more than 200 reports of torture, and 81 people were being held on June 7th as the deadly conflict raged in eastern Ukraine.

U.N. Human Rights Chief Navi Pillay says in the report today Ukraine’s “climate of insecurity and fear” has displaced 34,000 people, nearly half in Donetsk and Luhansk.
