German Chancellor Angela Merkel has warned that the ceasefire in eastern Ukraine is not stable, Reuters reports. She also said that she and US President Barack Obama are looking into ways to strengthen the peace deal.
"We stand by the agreement of Minsk and put a lot of importance on its implementation as soon as possible," Merkel said. "We still have no stable ceasefire and we must advance on the political process and we discussed in detail the next steps needed."
