Imam Sheikh Mohammad Tawhidi took to social media after the London terror attacks to support calls for a “temporary ban on Muslim immigration” to the West. The Iranian-born religious leader, who moved to Australia from Iraq aged 12, said unfettered Muslim immigration isn’t progressive, “it’s suicide.”

“I support a temporary ban on Muslims coming from the Middle East,” he said. He later told Daily Mail Australia that “unmonitored multiculturalism is to blame.”

Terrorism in the UK is growing week after week. Having extremists within our societies is not multiculturalism, it's suicide. — Imam Tawhidi ?? (@Imamofpeace) June 4, 2017

Sheikh Tawhidi, the “Imam of Peace,” made the remarks after Australian Senator Pauline Hanson took to social media to tweet: “Stop Islamic migration before it is too late.” In the U.S., then-candidate Donald Trump called for a temporary ban from Muslim countries, but as president has revised that policy to be regional. After the two most liberal courts in the land put a halt to the executive order, the Trump Administration asked the Supreme Court to reinstate the ban.

The imam said jihadists attend mosques that promote sharia law, which at its core is violent.

“The majority of mosques advocate for sharia law without removing the violent parts,” he said, going so far as to say the imam who preached to the three London terrorists needs to be held responsible.

“You need to investigate and shut down the mosque that this terrorist used to attend,” he tweeted to UK Prime Minister Theresa May.

An witness to the terror attacks on the London Bridge told reporters he saw three men stabbing people indiscriminately, shouting “this is for Allah.” The witness, who identified himself as Gerard, described the attackers as being in a “rampage.”

“They were stabbing everyone. They were running up and going ‘This is for Allah’,” he told BBC News. “They ran up and stabbed this girl – I don’t know how many times – 10 times, maybe 15 times. She was going, ‘Help me, help me’ and I couldn’t do nothing. I threw something – there was a bike on the floor. I threw something at them like a bike or a chair.”

Police called the London Bridge and Borough Market “twin terror attacks,” but said the Vauxhall stabbing was not related. As least 20 people had been taken to 6 hospitals for the attack on the London Bridge, and reports currently put the death toll at 6.
