London residents went to court on Monday to stop the government placing surface-to-air missiles on top of their apartment block during the Olympics, saying it could make them a target for attacks.
Britain's Ministry of Defence confirmed last week that the missile systems would be deployed at six sites across the capital during the Games to provide a "powerful deterrent" against a terror attack from the air.
Tenants of one of two blocks of flats near the Olympic Park in Stratford, east London, on which missiles will be based launched legal action last week, saying that the move would breach their human rights.
Lawyer Marc Willers, representing a group of residents from the Fred Wigg Tower in Leytonstone, east London, told a judge at London's high court the "unprecedented" move had caused them to fear for their safety.
"They have a fully justified fear that installation or deployment of the missile system on the roof of the Fred Wigg Tower gives rise to the additional risk that the tower itself may become the focus of a terrorist attack," he said.
Residents from the block of more than 100 local authority-owned homes are seeking an injunction to stop the systems being stationed there, claiming their rights have been breached because they were not consulted on the plans.
Defence Secretary Philip Hammond has said the MoD will defend the proceedings "vigorously" and is confident of defeating them.
Rapier and high velocity missile systems will be installed at six locations from mid-July and will remain there throughout the Games, the defence ministry has said.
Other steps being taken to protect the Olympics include mooring a helicopter carrier in the River Thames and stationing RAF Typhoon jets and Puma helicopters on the outskirts of London.
Britain's biggest-ever peacetime security force of more than 40,000, backed by a huge intelligence operation, will also guard venues, athletes and the millions of visitors expected to throng the British capital.
The MoD has said the missiles would only be used in the event of "specific orders from the highest levels of government in response to a confirmed and extreme security threat."
