Latest Developments in Ukraine: April 20
FIGHTING
* Russia's latest ultimatum to Ukrainian fighters holding out in Mariupol expired on Wednesday afternoon with no sign of mass surrender.
* Russia assaulted cities and towns along a boomerang-shaped front hundreds of miles long and poured more troops into Ukraine in a potentially pivotal battle for control of the country’s eastern industrial heartland of coal mines and factories.
* The Russian defence ministry has proposed that relatives of soldiers killed in Ukraine should have to apply to military rather than civilian authorities for compensation payments, imposing an extra level of secrecy around its war losses.
* Ukraine’s former prime minister says his country must win the conflict with Russia or “be exterminated.”
* Russia said on Wednesday it had conducted a first test launch of its Sarmat intercontinental ballistic missile, a new and long-awaited addition to its nuclear arsenal which President Vladimir Putin said would make Moscow's enemies stop and think.
HUMANITARIAN
* In less than two months since Russian troops started the war in Ukraine, 5 million Ukrainians have left their country and 7.1 million are displaced internally— the largest conflict-related internally displaced population in the world.
* Moscow has deported 500,000 people from Ukraine to Russia, a leading member of the parliament in Kyiv told European lawmakers on Wednesday, calling on the Red Cross to establish contact with those missing.
DIPLOMACY
* Ukraine is ready to hold a "special round of negotiations" with Russia in the besieged city of Mariupol without any conditions, negotiator Mykhailo Podolyak tweeted on Wednesday.
SANCTIONS
* The United States on Wednesday imposed sanctions on dozens of people and entities, including a Russian commercial bank and a virtual currency mining company.
