LONDON: Hundreds of thousands of demonstrators rallied in cities in Europe, the Middle East and Asia on Saturday to show support for the Palestinians as Israel's military widened its air and ground offensive on the Gaza Strip.

In one of the biggest marches, in London, aerial footage showed large crowds marching through the centre of the capital to demand the government of Prime Minister Rishi Sunak call for a ceasefire.

"The superpowers at play are not doing enough at the moment. This is why we're here: we're calling for a ceasefire, calling for Palestinian rights, the right to exist, to live, human rights, all our rights," said protester Camille Revuelta.

"This is not about Hamas. This is about protecting Palestinian lives," she added.

Echoing Washington's stance, Sunak's government has stopped short of calling for a ceasefire, and instead advocated humanitarian pauses to allow aid to reach people in Gaza.

Britain has supported Israel's right to defend itself after the Oct. 7 attack by the group Hamas that Israel said killed 1,400 people, mostly civilians.

The death toll in Gaza has climbed to 7,650 dead, also mostly civilians, since Israel's bombardment began three weeks ago, according to a daily report released on Saturday from the Palestinian health ministry.

There has been strong support and sympathy for Israel from Western governments and many citizens over the Hamas attacks, but the Israeli response has also prompted anger, particularly in Arab and Muslim countries.

In Malaysia, a large crowd of demonstrators chanted slogans outside the U.S. embassy in Kuala Lumpur.

Addressing hundreds of thousands of supporters at a huge rally in Istanbul, Turkish President Tayyip Erdogan said Israel was an occupier, and repeated his stance about Hamas not being a terrorist organisation.

Erdogan drew a sharp rebuke from Israel this week for calling the group "freedom fighters".

Iraqis took part in a rally in Baghdad and in the Israeli-occupied West Bank, Palestinian protesters in Hebron called on Saturday for a global boycott of Israeli products.

"Don't contribute to the killing of the children of Palestine," they chanted.

Elsewhere in Europe, people took to the streets of Copenhagen, Rome and Stockholm.

Some cities in France have banned rallies since the war began, fearing they could fuel social tensions, but despite a ban in Paris, a small rally took place on Saturday. Several hundred people also marched in the southern city of Marseille.

In New Zealand's capital, Wellington, thousands of people holding Palestinian flags and placards reading "Free Palestine" marched to Parliament House.

In London, special restrictions were in place restricting protests around the Israeli Embassy.

Saturday's march was mostly peaceful, but police said they had made nine arrests: two for assaults on officers and seven for public order offences - some of which were being treated as hate crimes.

Police estimated the turnout at between 50,000 and 70,000 people.

London police have faced criticism in recent days for not being tougher over slogans shouted by some protesters during another pro-Palestinian march in the capital last week, which drew about 100,000 people.
