LONDON (Dispatches) -- The Russian embassy in London on Monday roundly dismissed the “inappropriate statements” of British Foreign Secretary James Cleverly, who spuriously claimed Iran was sending armament and munitions to Russia for its military campaign in neighboring Ukraine.

“We categorically reject recent comments by Cleverly, who followed in the footsteps of U.S. authorities and accused the Russian Federation and Iran of some ‘sordid’ deals concerning the Ukraine crisis. The United Kingdom is well aware of the fact that the allegations about Iran’s military supplies to Russia lack any factual basis,” the diplomatic mission said in a statement.

“Russia, unlike certain Western governments, is invariably committed to compliance with national legislations as well as international principles as regards its cooperation with third countries,” it added.

The Russian embassy said the top British diplomat should be reminded of London’s and its Western allies’ massive military, technical, financial and propaganda assistance to Ukraine when talking about “sordid” transactions between Moscow and Tehran.

It said supplying Ukraine with Western weapons, which is taking place in clear breach of fundamental norms of export control, only led to prolongation of hostilities and an increase in civilian casualties as Ukrainian army forces used the military equipment to launch “de-facto terrorist strikes against civilian targets” on Russian territory.

“We are carefully recording all cases of London’s and its Western allies’ financial and military supplies to the Kiev regime, as well as planned military operations against Russian facilities and military personnel. Such criminal acts will naturally have specific legal consequences for all those involved,” the statement said.

The embassy also drew attention to Cleverly’s “utterly unfounded speculations” that Tehran violated UN Security Council Resolution 2231, which endorses the 2015 Iran nuclear deal – officially known as the Joint Comprehensive Plan of Action (JCPOA).

“If London is really concerned about implementation of the resolution, British authorities should pay meticulous attention to its true violator, the United States, whose unilateral withdrawal from the nuclear deal [in May 2018] has created serious challenges for global security,” the statement added.
