'Qatar's place is not in Khamenei's grave,' warns Dubai police chief in bizarre Twitter rampage

Dubai's head of security has lashed out at Qatar on social media accusing Doha of orchestrating a global conspiracy to destroy the Arab world. 

In a long series of crude and sectarian outbursts on Twitter, General Dhahi Khalfan on Thursday urged Qatar to return to the fold of other Gulf states.

"Little brother, today you have to come apologise in front of your big brother. Know that your natural place is with Saudi Arabia and that your unnatural place is in Khamenei's grave," Khalfan said, referring to Iran's supreme leader.

He tweeted out an image of Qatar's minister of culture praying at the mausoleum of the Ayatollah Ruhollah Khomeini, the late revolutionary leader of Iran, during a visit to the country.

"Qatar has opened up the doors to its land for Iran, allowing [Hizballah] and the Revolutionary Guard onto the banks of Saudi Arabia," he claimed.

He also accused Qatar of conspiring with Israel to bring down the regime of long-time Libyan leader Muammar Gaddafi in order to steal the North African country's oil wealth.

"Qatar is facing an Arab spring revolution that demands it pays for the destruction it has caused across the region through the inciting, funding and participation of [terrorism]," he added.

Saudi Arabia, the United Arab Emirates and its allies Egypt and Bahrain severed all ties with Qatar on June 5, accusing it of support for extremist groups – a claim Doha strongly denies.

They closed their airspace to Qatari carriers and blocked the emirate's only land border, a vital route for its food imports. They also ordered all Qataris to leave and their own nationals to return home.

On Wednesday, the ruler of Dubai urged Qatar to conform to a list of 13 stringent demands made by Saudi Arabia and its allies for an end to their blockade – in a lengthy series of rhyming couplets posted on Instagram.

Khalfan is no stranger to controversy, in the past he has backed US President Donald Trump's Muslim travel ban and called for the annexation Qatar.

He has also claimed to have made UFO sightings, as well as, come under fire for tweeting crude jokes about raping women.
