Iran and Russia's potential lethal pact over the war in Ukraine could have 'dire consequences' for the US, a security expert has warned.
This comes after Pentagon officials said they believe Iran supplied Russian forces 400 advanced attack drones, many of which have been used to allegedly bomb Ukrainian targets.
There are also fears more 'advanced weapons' could be handed over to Russia to be used in Putin's ill-fated war with its smaller neighbour.
