The US has released a number of photographs that appear to show the presence of Russian special forces in eastern Ukraine.
The pictures, supplied by Ukrainian diplomats, purport to identify well equipped Russian military in different cities in eastern Ukraine.
Washington says there is a broad consensus across the international community that Russia is engaged in a programme of destabilisation in the country.
Jen Psaki, is a spokesperson at the US State Department:
“Well, we’ve stated the case pretty strongly publicly before these photos were out there, before we were talking about them in terms of our belief that there is a strong connection between Russia and the armed militants that we’ve seen in eastern Ukraine and Crimea and other places. So, this is more just further photographic evidence of that.”
The Kremlin has yet to respond to the publication of the pictures.
Moscow has however repeatedly denied it is involved in agitation in Ukraine and has warned Kyiv against using force against pro-Russian protesters.
