Sir Keir Starmer is offering Hamas “a prize” by planning to recognise Palestine as a state, a British-Israeli woman whose brothers were kidnapped and killed by the terrorist group has said.

More than 1,000 demonstrators descended on London to demand the release of remaining hostages, clashing at times with pro-Palestinian protesters.

One demonstrator wearing a lapel calling for the release of the hostages was grabbed by the throat.

Police arrested three people during the demonstration.
