Masked pro-Palestinian protester stops play during Cam Norrie's Australian Open match by throwing leaflets at the court while security is nowhere in sight… before fans step in to escort her out!

A masked protester disrupted the Australian Open fourth-round tie between Cameron Norrie and Alexander Zverev on Monday by throwing “Free Palestine” leaflets onto the court.

The protester's leaflets were quickly taken away by officials on the pitch, but it was left to two fans who were at the protest to escort them out of Margaret Court Arena.

The British No. 1 was serving in the third set and preparing to win his game with an advantage to make it 4-2.

But both Zverev and Norrie were forced to stop and wait for the protest – which took place behind the German No. 6 seed – to clear at the back of the field.

Those present in the arena claimed that security was slow to act the independent reported that after the protester was ejected, the stadium erupted in applause.

The pamphlets appeared to emphasize “war crimes and genocide” and carried the slogan “Liberate Palestine” in an attempt to raise awareness of the ongoing conflict between Israel and Hamas in Gaza.

“While you are watching tennis, bombs are falling on Gaza,” the pamphlet read.

'Australia is a close ally of Israel. Australia is complicit in war crimes and genocide.

Monday's demonstration during the grand slam quarterfinals marks the latest attempt to use tennis' biggest platform — the majors — as a place to organize protests.

In July, Just Stop Oil protesters disrupted matches at Wimbledon, with Norrie's compatriot Katie Boulter also falling victim to an unexpected delay.

Group member Willian John Ward ran onto Court 18 during Boulter's clash with Daria Saville and threw orange confetti onto the hallowed grass.

The protester had bypassed numerous security checkpoints set up in an attempt to derail protest efforts by bringing in the confetti in a Wimbledon jigsaw puzzle box.

Grigor Dimitrov's match against Sho Shumabukuro's match was also disrupted during a similar protest earlier in the day, but the use of ticker tape instead of the group's signature orange fabric allowed play to resume quickly in both matches.

After the protest, Mr Ward said: 'I don't like making noise but I don't want my grandchildren, nieces and nephews to suffer. Right now, millions of people are being forced outside the conditions necessary to sustain human life.”

Last year, Wimbledon was also interrupted by protesters from Just Stop Oil, who threw orange confetti on Court 18

After being escorted from court, Ward was later arrested on suspicion of serious trespass and criminal damage.

The ground tried to combat future – or inspired – protests in a similar manner by banning the sale of souvenir puzzles in the official Wimbledon store.
