Ukraine's acting President is ordering security forces to resume operations in the country's east, and the Defence Ministry says a military aircraft was struck by gunfire over one of the tensest cities in the region.
The twin developments on Tuesday raised fears over whether last week's international agreement on easing Ukraine's crisis can succeed. The agreement calls for all sides to refrain from violence and for demonstrators to vacate public buildings. Pro-Russia insurgents in eastern Ukraine have rejected the agreement, arguing they were not party to it. Ukraine suspended its so-called anti-terrorist operation in the east after the agreement. President Oleksandr Turchynov said it must be resumed.
