Hawzah News Agency (London, UK) - Holding Palestinian flags and banners, the protesters were chanting “Free Palestine”, “Freedom Now” and “End Occupation” slogans.
Some of the placards held by the protesters read “Stand up For Gaza, Stop the Killing” and “Nakba70, We Are Returning”.
A small number of pro-Isareli protesters carrying Israeli flags also held a counter protest near the embassy located in South Kensington.
Jewish immigration to Palestine rose considerably during the British mandate period, which lasted from 1922 to May 14, 1948.
Ultimately, some 700,000 Palestinians fled their homes -- or were forcibly expelled by invading Jewish forces -- while hundreds of Palestinian villages and cities were razed to the ground.
The Palestinian diaspora has since become one of the largest in the world.
Until this day, Palestinian refugees remain scattered across Jordan, Lebanon, Syria and other countries, while many have settled in refugee camps in the Palestinian West Bank and Gaza Strip.
Last December, U.S. President Donald Trump sparked an international outcry when he unilaterally recognized Jerusalem as Israel's capital and vowed to relocate Washington's embassy to the flashpoint city -- a move scheduled for next Monday (May 14).
Tension has mounted on the Gaza Strip’s eastern border with Israel since March 30, when Palestinians began holding open-ended demonstrations to demand the “right of return” to their homes in historical Palestine from which they were driven in 1948.
Since the rallies began some six weeks ago, at least 48 Palestinian demonstrators have been martyred and hundreds more -- possibly thousands -- injured.
The Nakba will be protested with various activities -- which will take place in the West Bank, the Gaza Strip and in Arab villages inside Israel -- including seminars, marches and protests, according to organizers from the National Committee for the Commemoration of the Nakba.
May 15 will also be a day of “confrontation” with the Israeli army “in all border areas,” organizers said.
