"We call on Russia to avoid any further such testing. We also urge Russia to continue to work constructively with the UK and other partners to encourage responsible behaviour in space."
The BBC report that the US has previously raised concerns about the same satellite.
The BBC reported that the head of US space command, General Jay Raymond, said there was evidence "that Russia conducted a non-destructive test of a space-based anti-satellite weapon".
He said Russia "injected a new object into orbit" from a satellite.
Raymond added: "This is further evidence of Russia's continuing efforts to develop and test space-based systems and [is] consistent with the Kremlin's published military doctrine to employ weapons that hold US and allied space assets at risk."
