LONDON - A 24-year-old man appeared in court in London on Tuesday charged with planning an act of terrorism that involved running over a US serviceman in Britain.

Junead Ahmed Khan, from Luton north of London, is also charged with his younger 22-year-old uncle Shazib Ahmed Khan of planning to join Islamic State militants in Syria. The men, who were arrested a week ago, appeared at Westminster Magistrates' Court to be formally charged and were remanded in custody until another hearing.

The court heard that between mid-May and mid-July this year, Junead Ahmed Khan planned to kill a member of the US military by staging a car accident and running them over. Both men are also accused of planning a trip to Syria between August 2014 and May 2015, including looking into buying combat wear.

‘It is alleged that Junead Khan and Shazib Khan had been planning on travelling to Syria to join the proscribed organisation Islamic State in Levant (ISIL),’ said Deborah Walsh of the Crown Prosecution Service (CPS). ‘It is further alleged that Junead Khan was planning a terrorist attack on US military personnel in the UK and he has been charged with an additional terrorism offence to reflect this.’

The two men were arrested on July 14, along with another man in his 30s, who was later released without charge. ‘The arrests and searches were part of an ongoing investigation into Islamist-related terrorism,’ police said.
