"Iran -- fresh from real elections -- attacked by @POTUS in that bastion of democracy & moderation. Foreign Policy or simply milking KSA of $480B?" Zarif tweeted on Sunday.
Zarif was responding to remarks made by Trump during his visit to Saudi Arabia, in which the US president called on all nations to work towards isolating Iran.
The Iranian foreign minister was referring to a recent arms deal between the US and Saudi Arabia worth almost $110 billion immediately, and set to reach to $350 billion over 10 years, plus a series of other deals. Saudi Arabia is US arms dealers’ most important client and Washington’s number one ally in the Middle East.
Earlier, Zarif, in an editorial for the website of the London-based al-Araby al-Jadeed news network, advised Trump to discuss how to avoid another September 11 terrorist attack with the Saudi hosts in his first official visit abroad.
"(Trump) must enter into dialogue with them about ways to prevent terrorists and Takfiris from continuing to fuel the fire in the region and repeating the likes of the September 11 incident by their sponsors in Western countries," Zarif wrote.
Hundreds of Americans affected by the September 11, 2001 terrorist attacks have recently filed a lawsuit against Saudi Arabia over its alleged role in the incident, demanding reparations from the Saudi monarchy.
In addition, the lawsuit also argued the September 11 attacks were not possible without the involvement of the Saudi royal family.
Of the 19 hijackers who allegedly carried out the 9/11 attacks, 15 were Saudi nationals.
Available evidence suggests some of them were linked to high-ranking Saudi officials.
