TEHRAN – Iran’s Foreign Ministry has accused the U.S. government of supporting the ISIS terrorist group, describing the U.S. and ISIS as “brothers in arms.”

“It's a well-documented fact, which's been admitted by Trump, that U.S. has had a crucial role in the rise of terrorism in our region, from AQ to ISIS. Not surprising that the US assassination of General Soleimani was cheered by ISIS: brothers in arms,” the Iranian foreign ministry said in a tweet on Saturday.

The foreign ministry also posted a video showing Trump addresses a campaign rally in which he says that former U.S. Secretary of State “Hillary Clinton created ISIS with Obama.” The video also shows that the commander of Iran’s elite Quds Force, General Qassem Soleimani was an “anti-terrorism champion” whose assassination only benefited the ISIS terrorist group.

This week marks the first anniversary of the assassination of the top Iranian general last year. General Soleimani was assassinated in an American drone strike on January 3, 2020, along with his comrade Abu Mahdi al-Muhandis, the deputy head of Iraq’s Popular Mobilization Forces (PMF), near Baghdad’s international airport. The strike was ordered by U.S. President Donald Trump, a reckless move that brought Iran and the United States close to an all-out war as General Soleimani was an influential figure in Iran and beyond. In response, Iran showered a U.S. airbase in western Iran with missiles, causing brain injury among dozens of American servicemen.

Earlier on Friday, the Iranian foreign ministry republished an assessment by Agnes Callamard, the UN Special Rapporteur on Extra-Judicial Executions, on the assassination of General Soleimani saying that the U.S. strike against the general was a blatant violation of international law.

According to Callamard, the strike was clearly a strike against the armed forces of another state and it was a use of force against Iraq and a violation of its sovereignty. Callamard noted that the strike also was in violation of the UN charter.

The Iranian foreign ministry also said that the strike was against international law.

“By committing a craven act of terror against Gen Soleimani, the US violated int'l law & the UN Charter in a blatant violation of Iraqi sovereignty. The US' lawlessness in full show. Iran won't rest until bringing those responsible to justice,” tweeted the foreign ministry.

Iran has long warned that it will take revenge against the U.S. for assassinating the commander of the Quds Force. Iran has recently said that some people inside the U.S. may move to avenge the assassination.

“By committing this crime, you [the U.S.] created a job for all freedom-seeking people across the globe. Be sure that it is possible that some people will be found inside your home to respond to your crime,” General Soleimani’s successor Brigadier General Esmaeil Qaani said on Friday. “Those who committed this crime should know that throughout the world there would be a man who will punish the cowards behind this crime.”

Iran also said that it will work to expel the U.S. from the region.
