Thousands of Gaza offensive protesters have held a “red line” rally near the White House, voicing anger at what they said is US President Joe Biden’s tolerance of Israel’s bloody military campaign against Hamas, Reuters reports.

Chanting “From DC to Palestine, we are the red line,” the demonstrators held a long banner scribbled with the names of Palestinians killed by Israeli forces, as the fighting enters its ninth month.

The White House said in May that a deadly Israeli strike on Rafah did not cross a “red line” that Biden had seemingly set two months earlier when asked about a potential invasion of the southern Gazan city.

“I no longer believe any of the words that Joe Biden says,” said protester 25-year-old Zaid Mahdawi from Virginia, whose parents are Palestinian. “This ‘red line’ in his rhetoric is rubbish… it shows his hypocrisy and his cowardice,” Mahdawi told AFP.

The protesters — almost all wearing red clothing — held Palestinian flags and signs saying “Biden’s red line was a lie” and “Bombing children is not self-defence.”
