Up to 10,000 people attended a rally in Trafalgar Square on Saturday of last week.
Speakers included Lindsey German, the convenor of the Stop the War Coalition, who condemned Israel’s attacks and the West’s continued support for it.
“This ceasefire is not a ceasefire in any meaningful sense if the Palestinians don’t have the right to defend themselves,” she said. “Self defence is no offence.”
As the rally closed, hundreds of mainly young people decided to march to the Israeli embassy.
They were blocked by a line of police and after nearly an hour of confrontation they managed to break through and marched along Charing Cross Road and down Shaftesbury Avenue.
At the core of the protest were about 300 mostly Asian school and college students.
Eventually police surrounded the majority of demonstrators and brought the protest to an end. But the spontaneous march had brought much of London’s West End to a standstill for more than an hour.
