Pro-Palestine demonstrators have been arrested after red powder paint was thrown on Tower Bridge during the London Marathon.
Youth Demand supporters jumped over the barriers and threw the substance in front of the men’s elite race at around 10.35 am.
An image shared by the group shows two people standing in the middle of the road wearing t-shirts that said: “Youth Demand: Stop Arming Israel.”
Marathon event staff intervened to remove the protesters and the race passed unobstructed, the Metropolitan Police said.
It added: “He was quickly supported by police officers who arrested the protesters on suspicion of causing a public nuisance.
“They remain in custody.
“The paint appears to be chalk-based and is not expected to present a hazard to runners yet to pass this point”.
Youth Demand named the two activists as Willow Holland, 18, from Bristol, and Cristy North, a live-in carer from Nottingham.
Holland was quoted by the group as saying: “I am taking action with Youth Demand because I have run out of other options: thousands are being killed in Gaza, our Government is making no effort to stop it and no other course of action, marches or rallies, has worked.
“I refuse to be complicit in a genocide funded by our politicians.”
Youth Action said the demonstration came after the UN’s World Food Programme (WFP) announced its food stocks in Gaza have been completely “depleted” by Israel’s blockade.
According to the group, North said: “I’m taking action today at the London marathon because the people in Palestine are running out of time.
“We have tried all other avenues to get the Government to stop arming Israel and yet our Government is still enabling a genocide.
“They are making the UK people complicit in breaking UK domestic law by using our taxes to arm a genocidal state, breaking humanitarian international law.”
The BBC TV feed cut to the elite men’s race moments after the leaders had crossed Tower Bridge and there appeared to be no impact on the race.
Hugh Brasher, chief executive of London Marathon Events, said: “It’s very disappointing that two people attempted to disrupt the London Marathon which does so much good, raises so many millions for charity, brings so much joy and brings communities together.
“Our staff and the police intervened immediately and the event was not impacted in any way.”
More than 56,000 participants are expected on the 26.2-mile course through the capital on Saturday for the 45th TCS London Marathon.
