Iran's Foreign Minister Mohammad Javad Zarif has slammed the United States' “sheer hypocrisy” for seeking to stop Iran's defensive missile program while flooding the Middle East region with all kinds of weapons.

Taking to his official Twitter account on Monday, Mohammad Javad Zarif said the pressure put on Iran by the West to dismantle its missile program comes at a time when the US and major European countries encourage their allies in the Middle East to buy more weapons.

"Customer Service’ pledge by US/E3 arms producers: Buy our weapons & our governments will provide after-sales support by pressuring your neighbor to dismantle its defenses,” Iran's Foreign Minister added.

Zarif noted that Washington and its European allies are whining about Iran's defensive missile program while pouring hundreds of billions of dollars of arms into the region.

About 14,000 people have been killed since the onset of Saudi Arabia’s military campaign against Yemen in March 2015.

Much of the Arabian Peninsula country's infrastructure, including hospitals, schools and factories, has been reduced to rubble due to the war.
