Dozens of demonstrators gathered at the embassy in Princes Gate, Knightsbridge, on Sunday afternoon.
And GB News' Ellie Costello, reporting from the scene on Monday morning, told viewers: "For the next few days, we will see a very heavy police presence here."
It comes as footage of protests in Iranian cities spreads across the world, sparked by the death of 22-year-old Mahsa Amini in custody after being detained by Iranian morality police.
Scotland Yard said the disorder at Sunday’s protest initially broke out in the immediate vicinity of the embassy before moving to Marble Arch and then to Maida Vale where the Islamic Centre of England was targeted.
The force said several officers were hurt during the protest, five of whom are in hospital with serious injuries including broken bones.
12 people were arrested on suspicion of violent disorder.
Police have put a Section 35 dispersal order in place for the next 48 hours in the area impacted by the disorder.
Commander Karen Findlay said: “We respect the right of people to protest peacefully and always work with organisers to make that possible, but we will not tolerate unprovoked attacks on our officers as we have seen today or protest that leaves other communities feeling unsafe.
“We have officers in hospital tonight because they were attacked in what was a significant outbreak of violent disorder. We will make sure they get the support they need.
“We have already made a number of arrests, but we know there are people who were not caught tonight who committed serious offences.
“In the coming days, we will be using all the tools at our disposal – including CCTV and other footage – to identify those people and bring them to justice.”
It comes after Iran’s foreign ministry said on Sunday it had summoned Britain’s ambassador Simon Shercliff over what it described as a hostile atmosphere created by London-based Farsi language media outlets.
