Moscow threatens retaliation after Andy Burnham says UK will help Ukraine start producing long-range missiles

Russia has said it could retaliate against the UK for its support of Kyiv by striking military targets inside and outside Ukraine, amid reports that the director of the CIA warned the Kremlin against attacking Nato during a secretive visit this week.

Andy Burnham, Britain's prime minister, said on Monday the UK would allow Kyiv access to classified technology to start its own production of Storm Shadow long-range cruise missiles. France has also agreed to supply missile technology. Maria Zakharova, Russia's foreign ministry spokesperson, said on Thursday Britain and France were playing with fire".
