A black cab protest scheduled for tomorrow has been postponed out of respect for the attacks in Brussels.
The United Cabbies Group was planning a protest against government interference in the regulation of London taxies.
However, in light of terror attacks that unfolded in Brussels, Belgium, earlier today, the group has rescheduled the protest.
As many as 34 people have been killed and more than 130 wounded in what is thought to be a pair of coordinated suicide attacks at Zaventem Airport and Maalbeek metro station in Brussels today.
"In light of the tragic events unfolding in Brussels and as a mark of respect for the victims the UCG have postponed tomorrows planned action," the group said.
"There are also heightened security measures being put in place that requires specific policing tactics that will require additional resources.
"We were asked by the police to carefully consider the implications on stretched resources as our previous protests have stretched police resources to the limit.
"It is not our intention to place London'ss security at threat and we have informed the Police tomorrows protest is postponed."
Police believe at least 14 people were killed in two explosions at the airport, which is thought to have taken place near to an American Airlines desk. A further 80 people are thought to have been wounded in the blast. One British national is among those injured.
Met Police assistant commissioner Mark Rowley said police forces across the UK have already increased policing presence "at key locations, including transport hubs".
"This is not in relation to any specific information or intelligence," Rowley said in a statement this morning.
"In London specifically, the Metropolitan Police Service has mobilised additional officers, who will carry out highly visible patrols at key locations around the capital, including the transport network."
