There were also sightings of demonstrators wearing illustrations of paratroopers on their clothes, believed to be a reference to Hamas terrorists who used improvised aerial craft to infiltrate Israeli territory last Saturday.
While number of marchers could not be confirmed, aerial footage of the event, which started at the BBC's headquarters off Oxford Street before heading to Westminster, showed what looked like thousands of protestors.
The BBC's New Broadcasting House was also covered in red paint by the Palestine Action group, who said that the BBC was "manufacturing consent for Israel’s war crimes.”
Former Labour leader Jeremy Corbyn spoke at the event alongside Palestinian representative to the UK Husam Zomlot.
The Metropolitan Police made seven arrests during the protest, on suspicion of breaches of the face covering order as well as public order offences.
Earlier, the Metropolitan Police said that they would arrest any protesters who deviate from an official route or carry signs supporting Hamas or any other proscribed terror groups.
Police also warned that those found supporting Hamas will be arrested, adding that they have assigned more than 1,000 officers to police the event taking place today in central London.
Authorities also said they have introduced powers to compel any demonstrator to remove facial coverings around the area of the protest and the Israeli embassy until 10 pm tonight.
