David Cameron spoke to the President of the European Council, Donald Tusk, about ongoing violence in Eastern Ukraine.
A Downing Street spokesperson said:
The President of the European Council, Donald Tusk, called the Prime Minister this evening to discuss how the EU should respond to the ongoing violence in Eastern Ukraine. Both expressed deep concern that since the ceasefire Russian-backed separatists have continued to attack Debaltseve, forcing the Ukrainian army to conduct an orderly withdrawal, and that the separatists have violated the ceasefire in other locations in Donetsk and Luhansk.
They agreed that the EU should make clear to Russia that the pro-Russian rebels must abide by the ceasefire. Mr Tusk said that the EU will be scrutinising the situation on the ground very closely in the coming days and both leaders agreed that European Member States would need to review the EU’s response accordingly.
