London: Five men have been charged here in connection with an alleged Islamic State (IS) plot to carry out a drive-by gun attack against Scotland Yard officers.
Four of the group are said to have sworn allegiance to IS and to have planned to use a moped to carry out the shooting on the streets of London.
They are accused of using Google Street View to conduct "hostile reconnaissance" of Shepherds Bush police station and White City Territorial Army barracks, both in west London, 'The Times' reported.
It is also alleged that the group shared Instagram photographs of two Metropolitan Police officers and two police community support officers (PCSOs).
Mark Dawson, for the prosecution, told Westminster magistrates' court that the alleged plot was "to shoot, to kill, police officers or soldiers on the streets of London".
Police across the country were warned last week to increase their personal vigilance because of the heightened threat of terrorism.
The charges come after a series of armed counter-terrorism raids across London last week and the recovery last month of a handgun, silencer and ammunition.
The group was brought to court in two police vans, surrounded by marked cars and with a helicopter hovering overhead.
The men facing terrorism charges are Tarik Hassane, 21, a medical student at university in Sudan; Suhaib Majeed, 20, a physics student at King's College London; Momen Motasim, 21; and Nyall Hamlett, 24.
They appeared briefly alongside -Nathan Cuffy, 25, who is charged with supplying the handgun and ammunition, with a silencer to Hamlett.
