Valeriy Heletey, Ukraine's Defence Minister, accuses Russia of launching a "great war".
A rally of war veterans in Kiev calls for Ukraine to abandon the Minsk II ceasefire agreement and to declare war on pro-Russian separatists in the Donbass region. Despite two ceasefire agreements since September, combat operations, including the use of heavy artillery and ballistic missiles, never stopped.
Russia and Ukraine together with the United States and the European Union sit down for emergency talks in Geneva. All four agree that "illegal military formations in Ukraine" must be dissolved, and that everyone occupying buildings must be disarmed and leave them. There would be an amnesty for all anti-government protesters under the agreement.
