A deal aimed at ending the fighting in eastern Ukraine has been agreed, following marathon talks in Belarus.
The leaders of Russia, Ukraine, Germany and France announced that a ceasefire would begin on 15 February.
The deal also involves the withdrawal of heavy weapons from the front line, but some issues remain to be settled.
The leaders said pro-Russian rebels in eastern Ukraine had signed the agreement. Thousands of people have died in almost a year of fighting.
French President Francois Hollande said he and German Chancellor Angela Merkel would ask their European Union partners to support the deal at a summit later on Thursday.
The agreement – reached after 17 hours of negotiations in Minsk – includes:
Ceasefire to begin on 15 Feb
Heavy weapons to be pulled out
All prisoners to be released
Mr Poroshenko said Ukraine would establish control of international border by the end of the year
However the deal was not a “comprehensive solution” nor a “breakthrough”, Germany’s foreign minister said. (BBC)
