Watch as Pro-Palestine protesters march in London on Saturday, 25 November, after the first hostages were freed in a four-day ceasefire between Israel and Hamas.
Under the agreement, a total of 50 Israeli hostages will be freed in exchange for 150 Palestinians imprisoned in Israel.
Thirteen Israeli women and children held in captivity by the militant group in Gaza were released on Friday evening, while 39 Palestinians were released from Israeli prisons.
Footage showed an emotional reunion between a nine-year-old boy who was held hostage by Hamas hugging his father for the first time after being released.
Police at Saturday’s march, which was predicted to draw thousands to London, were expected to hand pro-Palestine protesters leaflets for "clarity" on potential crimes.
Around 1,500 officers were due to be deployed for the demonstration.
The Metropolitan Police were expected to hand out leaflets warning against using language or images "likely to land you in jail".
Deputy assistant commissioner Ade Adelekan said: “This sets out that anyone who is racist or incites hatred against any group should expect to be arrested. As should anyone who supports Hamas or any other banned organisation.”
