UKRAINE – Ukraine has become “very volatile” since Prime Minister Arseniy Yatseniuk resigned, the head of the Council of Europe said on Monday, calling for the swift formation of a new government and speedier progress on reforms. Yatseniuk tendered his resignation on Sunday, opening the way to seeking a more stable government for Ukraine which is struggling with an economic crisis and a conflict with Russia-backed rebels in its eastern regions. “The situation in Ukraine is now very volatile,” Thorbjoern Jagland told reporters in Brussels. “It is urgent that they establish a new government and even more urgent that they speed up the reform process.”(Reuters)…[+]
