The Russian Foreign Ministry said on Thursday that Moscow "did not accept threats" after U.S. President Donald Trump said he would give Moscow 50 days to reach a ceasefire in Ukraine or face sanctions.
Trump on Monday announced a toughened stance against Russia over its war in Ukraine, setting out the ceasefire ultimatum and promising a fresh wave of missiles and other weaponry for Kyiv.
Maria Zakharova, a spokeswoman for the Russian Foreign Ministry, said on Thursday that Trump's decision to supply Ukraine with new missiles was a signal to "continue the slaughter" and a rejection of peace initiatives.
