One man standing in Trafalgar Square yesterday held a Palestinian flag with a placard reading, 'Stop doing what Hitler did to you', while a poster held by a woman read, 'Israel, the new Nazi state'.
Another sign in London referred to 'Holocaust Part 2' and another - referring to Israel's Prime Minister - read 'Netanyahu surpasses Hitler in barbarism'.
Pro-Palestine activists burned Israeli flags outside the nation's embassy in the capital, as London saw a consecutive weekends of anti-Israel protests.
Tens of thousands of demonstrators gathered in central London for a second weekend in a row as they called for an 'urgent' resolution to the Israeli-Palestine conflict.
Loud chants of 'Israel is a terrorist state' could be heard as the activists weaved their way through the capital, setting off flares and blocking traffic in the process.
The large group, situated close to Victoria Embankment, stretched across the surrounding roads as dozens of police officers watched on.
