Poroshenko: Threats of war still hang over us
The threat of war still exists in Ukraine and new fighting could break out at any time, Ukrainian President Petro Poroshenko said at the International Conference in Support of Ukraine in Kyiv on Tuesday.
We still live under the threat of war, and it is the reality. The war may break out at any moment, but we are willing to do our utmost to avoid every doubt or retreat, he said.
"Thanks to your help and your unity, we will find a peaceful resolution to the situation in Donbass," Poroshenko said, when delivering his speech.
"The Minsk agreements aimed at resolving the situation in the east of the country should be fully implemented with the coordination role of Ukrainian partners," he stressed.
OSCE observers once again refused access to Shyrokine
PRD rebels refused access for OSCE monitors to the village of Shyrokine near Mariupol yet another time on Monday, a statement on the OSCE page on Facebook reads.
"Yesterday, the so-called "PRD" did not allow a SMM team into the eastern part of Shyrokine for the third time in four days," a report reads.
In turn, Deputy Head of OSCE Mission to Ukraine Alexander Hug added that the PRD leadership had agreed free access for the mission, but a local rebel commander prevented monitors from accessing the eastern part of Shyrokine.
Hug reiterated that the SMM access to all Ukrainian areas was not a subject to negotiations and that preventing OSCE monitors from accessing the area contradicted the mandate, which was granted the SMM by 57 OSCE member-countries, including Ukraine and the Russian Federation.
