Gaza protestors clashed with police in west London during a second weekend of rallies, leaving one officer knocked unconscious and two more injured as up to 20,000 protestors swarmed around the Israeli Embassy in Kensington.
A 'hard core' of campaigners threw sticks, stones and barriers at police during a demonstration against the ongoing carnage in Gaza on Saturday afternoon.
Top cops, who are spending thousands to protect the embassy, have slammed the troublemakers who they claim 'have set out to deliberately confront and antagonise police officers'.
Commander Bob Broadhurst said: "A hard core of demonstrators are undermining the cause of the vast majority of people on this demonstration, who are law abiding citizens wishing to protest peacefully.
"We are very disappointed by the irresponsible and criminal actions of those who have challenged police by ripping apart security barriers and throwing objects at them."
A Met police spokesman confirmed that one cop was left unconscious while others were left with facial injuries.
One male was arrested on suspicion of aggravated trespass. There were two further arrests, one for assault on a police officer.
