Iran has transferred new long-range missiles to proxy groups in Iraq over the past week, defying hopes that the anti-American militias would disarm amid concern of an escalation with US President Donald Trump, according to a Tuesday report, amid preparations for high-level US-Iran nuclear talks in Oman Saturday.

Axar.az reports, citing Times of Israel, the deliveries from the Islamic Revolutionary Guard Corps’ air force include surface-to-surface missiles that could reach as far as Europe, as well as shorter-range Quds 351 cruise and Jamal 69 ballistic missiles, The Times of London reported, citing regional intelligence sources involved in monitoring the Iran-Iraq border.

A source cited by The Times said the new long-range models had never before been given to Iraq’s separatist pro-Iranian militias, which last year killed US and IDF troops in drone strikes on military bases in the region.

“It’s a desperate move by the Iranians, risking the stability of Iraq,” said the source.
