US Secretary of State Antony Blinken has arrived in Kyiv on an unannounced diplomatic mission to reassure Ukraine it has American support as it struggles to defend against increasingly intense Russian attacks.

The visit comes less than a month after Congress approved a long-delayed foreign assistance package that sets aside $60bn in aid for Ukraine.
