As part of the "overarching security plan," the Civil Aviation Authority (CAA) has introduced restrictions on flights by drones and other aircraft below 2,500 feet (762 m).

Only emergency vehicles and civil planes going to airports will be able to operate between April 21 and April 24. All other aircraft including "any small balloon, any kite weighing not more than two kilograms, any small unmanned aircraft and any parachute including a parascending parachute" will fall under the restrictions.

Obama and the first lady are visiting the UK to meet Prime Minister David Cameron, visit the Queen in Windsor and take part in a town hall meeting.

Earlier this week, a British Airways plane carrying 132 passengers and five crew was hit by an unmanned aircraft at about 1,700 feet (580m) while flying over the area of Richmond Park, in southwest London.
