Washington confirmed the day before that it had sent Ukraine a variant of the ATACMS missile with a range of 300 kilometers (190 miles), while France and Britain have respectively supplied SCALP and Storm Shadow missiles, both of which have a range of about 250 kilometers.

"In terms of Taurus... this is a decision for Germany," a senior US defense official told journalists when asked if the provision of long-range ATACMS could clear the way for Taurus missiles to be sent to Kyiv.

"But certainly the US provision of ATACMS as well as prior decisions by the UK and France to provide long-range cruise missiles, we would certainly hope that this would be a factor," the official said, speaking on condition of anonymity.

Kyiv has long pushed for Germany to provide it with Taurus missiles -- which can reach targets up to 500 kilometers away -- to help its fight against invading Russian forces.

But Berlin has declined to send the missiles, fearing that it would lead to an escalation of the more-than-two-year-old conflict.
