Australian journalist attacked live on-air, man 'yells Allahu Akbar', makes 'stabbing motions'

An Australian journalist has been attacked live on-air in London while covering protests in Europe sparked by the death of Minneapolis man George Floyd.

Nine's Europe correspondent Sophie Walsh was speaking during a live cross to Adelaide when she suddenly began screaming and swearing. In the background, footsteps can be heard. Walsh then begins apologising and sounds clearly distressed.

While footage of the protests were on display during the incident and the attack wasn't visible, Walsh made viewers aware of what happened.

"Sorry, sorry, sorry. I just… I just had someone come up and try and... yeah. Sorry. Yeah, yeah. A man just came up and grabbed me. He is okay. He is not armed. A man just came up and grabbed me though."

The broadcaster later reported that a man approached her and "yelled the words" Allahu Akbar while "making motions to stab her". This can't be clearly heard on Nine News Perth's footage.

The man in question was chased down by camera operator Jason Conduit with a light stand and detained by bystanders. Police soon arrived and arrested him for threats to kill and possessing an offensive weapon.

"It's unclear whether the man was armed with a screwdriver," Nine reported.

Walsh later tweeted to say that she was "shaken but okay". 

In a statement, broadcaster said Nine News appreciated the "enormous pressure our international correspondents are under and is offering Sophie Walsh ongoing support".

"Sophie is grateful for the outpouring of support she has received from the public and wishes to reassure our viewers that she is safe and well."

It's not the first time an Australian television crew has been attacked covering the protests. In Washington DC on Tuesday, a 7 News team was turned on by police. The camera operator, Tim Myers, was bashed with a riot shield while journalist Amelia Brace was hit with a baton. 

Demonstrations have been sparked worldwide after Floyd had a police officer kneel on his neck for nearly nine minutes. Many of the protests, including in New Zealand, have occurred under the Black Lives Matter movement, calling for an end to racism and police brutality.

The police officer film kneeling on Floyd has been charged with murder.
