The future of US support for Ukraine is being pushed further into doubt, with National Security Adviser Mike Waltz confirming on Wednesday that the US has paused intelligence sharing with Ukraine.
"We have, we have taken a step back," Waltz told reporters when asked about suspending intelligence sharing.
He added that the Trump administration was pausing and reviewing "all aspects of this relationship".
French President Emmanuel Macron later announced a meeting of European army chiefs in Paris next week, saying in a televised speech that France must be prepared to move forward without US help.
