Ukraine president: “Once again, this vile strike by Russia demonstrates the need for increased pressure on Moscow and additional sanctions.

“No matter how much the Kremlin denies their effectiveness, sanctions do work – and they must be strengthened.

“They must target everything that enables such attacks to continue. It is also crucial that the world does not remain silent about them. I thank everyone who has supported our people.

“We value the fact that President Trump, European leaders, and other partners clearly see what is happening and condemn Russia.”
