Iran's top leader's Twitter account has been shut down after he threatened to retaliate against former US President Donald Trump.

On Friday, Ayatollah Khamenei took to Twitter to taunt Trump, saying he would avenge the assassination of Iranian military commander General Qaseem Suleimani.

In the tweet, Khamenei posted a picture of a man with Trump's face playing golf in the shadow of a fighter jet or drone.

Khamenei tweeted in Persian, "Revenge forced." He wrote the word revenge in red letters. He further wrote, "Suleimani's assassins and those who killed him will have to pay the price."

Following the tweet, Twitter closed Khamenei's Twitter account. Khamenei has claimed that the US Department of Defense killed Suleimani "on the orders of the president."

US media reported that Suleimani and Iranian-backed rebel leaders were attacked as they were leaving the airport in two cars.

Suleimani was assassinated in Baghdad a year ago. Suleimani is said to have come to Iraq from Syria or Lebanon. General Suleimani was killed in a US airstrike while in his car. 

The then US President Trump claimed that Suleimani was responsible for the killing of millions of people.

After his death, Khamenei threatened to retaliate. Soon after Suleimani was killed, Iran fired some missiles at a US airbase in Iraq. 

Suleimani was an important figure for Iran and worked directly under the leadership of Supreme Leader Khamenei. The death of Major General Suleimani has raised tensions in the Middle East, including Iran. 

Many people now objected to Khamenei's tweet and demanded that his Twitter account be closed.

Earlier, Twitter shut down Trump's Twitter account permanently. Twitter has accused Trump of inciting violence after a violent attack on the US Congress on June 6.

But Twitter has not yet commented on the closure of Khamenei's account.

Who is Qaseem Suleimani?

Since 1998, Suleimani had led a special squad called the Quid of Iran. The group is said to be carrying out secret activities outside the country.

General Suleimani played a key role in perpetuating Bashar al-Assad's rule in Syria and in the fight against IS in Iraq. He fought in the Iran-Iraq war in the 1980s.

Suleimani, 62, was considered the second most powerful leader after Supreme Leader Ayatollah Khamenei. The Quid Force, the highest unit of Iran's Revolutionary Guard Corps, reported to Ayatollah Khamenei and considered Suleimani a national hero.

During his 21-year leadership in Quid, Iran is believed to have strengthened Hezbollah and expanded pro-Iranian militant groups in Lebanon.

It is said to have increased its military presence in Iraq and Syria and implemented a plan of action against militant groups in Syria's long civil war.
