ANTI-Israeli chants and flag-waving could result in police action, the Home Secretary has warned.

Suella Braverman told chiefs that “context is crucial” when policing pro-Palestine demonstrations.

She warned normally legal actions “may not be legitimate?.?.?.?when intended to glorify acts of terrorism”.

Hamas is a proscribed terror group in the UK, meaning any show of support is illegal.

Ms Braverman said: “It is not just explicit pro-Hamas symbols and chants that are cause for concern.

“I would encourage police to consider whether chants such as ‘from the river to the sea, Palestine will be free’ should be understood as an expression of a violent desire to see Israel erased from the world, and whether its use in certain contexts may amount to a racially aggravated section five public order offence.”

That is punishable by a fine of up to £2,500.

Ms Braverman also urged cops to monitor online offending.

She added: “I would encourage police to give similar consideration to the presence of symbols such as swastikas at anti-Israel demonstrations.

“Behaviours that are legitimate in some circumstances, for example the waving of a Palestinian flag, may not be legitimate such as when intended to glorify acts of terrorism.”
