Snipers will line rooftops as part of the security measures for the King's Coronation next month. Anti-drone units will also be deployed.
Thousands of police officers will be deployed to London's streets on May 6 as part of a huge security operation - dubbed Operation Tower of London - to guard the Crown Jewels from any potential thieves. They will be backed up by elite teams of armed guards, snipers and the military.
Counter-drone radar units will also be set up along the King and Queen's procession route, as well as devices to block signals between pilots on the ground and their aircraft. The Civil Aviation Authority has imposed a “no-fly zone” over Central London, banning aircraft from flying below various altitudes in certain areas on the afternoon.
