Russia must not escalate the conflict in Ukraine with false claims that Kyiv is planning to unleash a so-called "dirty bomb", the head of NATO warned Monday.

"Our countries made clear that we all reject Russia's transparently false allegations that Ukraine is preparing to use a dirty bomb on its own territory," the US State Department said in a joint statement with the British and French governments.

The specter of the ISIS group obtaining a "dirty bomb" will loom over a top-level nuclear security summit hosted by President Barack Obama in Washington on Thursday and Friday.
