Following on from our post below, Antony Blinken has said the US will provide an additional $2bn (£1.5bn) in military funding to Ukraine.
Speaking from Kyiv, where the secretary of state is visiting, he said the additional fund will be able to provide more weapons and investment in Ukraine's industrial base.
"We are rushing ammunition, armoured vehicles, missiles and air defences to get them to the front lines," Mr Blinken said.
The secretary of state said the US is "intensely focused" on providing patriots and other forms of air defence systems, which Volodymyr Zelenskyy has persistently asked allies for.
He said support is coming from the US at a critical time for Ukraine - which is facing fierce levels of fighting in the north, as Moscow targets the region of Kharkiv.
When asked if he would support US weapons being used to strike places inside Russia, he said: "We don't encourage this, but Ukraine has to make the decision for itself."
