Clashes broke out Tuesday between police and protesters outside the Israeli embassy in Mexico, rallying against the country's military offensive in the southern Gazan city of Rafah, AFP journalists said.
Some protesters covered their faces and threw stones at riot police who blocked their path to the diplomatic complex in the city's Lomas de Chapultepec neighborhood.
Around 200 people joined the "Urgent action for Rafah" demonstration, about 30 of whom started to break down barriers preventing them from reaching the Israeli mission.
Police officers deployed tear gas and threw back the stones hurled at them by protesters.
The demonstration was called in response to an Israeli strike which ignited an inferno in a displacement camp outside Rafah, killing 45 people according to Palestinian officials.
UK police arrest 40 after pro-Palestinian rally
UK police on Wednesday said that 40 people had been arrested and three officers injured after protesters refused to disperse following a demonstration in London over Israel's latest offensive in Gaza.
The British capital's Metropolitan Police Service said the individuals were arrested late on Tuesday for offences including breaching public order conditions, obstructing roads and assaulting emergency workers.
It said two officers sustained minor injuries after being assaulted while a third, who was struck by a bottle thrown from within the crowd, suffered a "serious facial injury".
The Met, as the force is widely known, said an investigation was under way to identify who threw the bottle.
Police had approved plans for the early evening protest -- organised by a coalition including the Palestine Solidarity Campaign -- outside the gates of Downing Street in central London.
But it imposed conditions including that the rally end by 8:00pm (1900 GMT).
Up to 10,000 people attended, and the "vast majority" had left by the required time, but a group of around 500 remained to continue protesting, according to police.
"Officers engaged extensively before making a number of arrests for failing to comply with conditions," the Met said in a statement.
"As they moved in, some in the crowd resisted physically requiring officers to use force to extract those who had been arrested."
Further arrests followed later in the evening after the remaining demonstrators launched a breakaway march and were eventually corralled outside a train station, the Met said.
Israel's renewed military operations in Gaza, concentrated on Rafah, have sparked fresh protests in London and other cities around the world.
The British capital has seen frequent marches protesting Israel's response to the deadly Hamas attack on its territory on October 7, stoking controversy and political debate over how they should be policed.
They have passed off largely peacefully, but police have made arrests at many for various offences, including anti-Semitic chanting and banners, promoting a proscribed organisation and assaults.
