Body of Norwich soldier flown home
The body of a soldier who was killed in Afghanistan is due to be returned to the UK later.
Private Lewis Hendry from Norwich, was from 3rd battalion the parachute regiment, will be flown into RAF Lyneham in Wiltshire.
He died after being shot on patrol in the north of Nad-e Ali district of Helmand Province on 9th February, just three days before his 21st birthday.
His parents paid tribute to him, saying he had a "true heart of gold'' and a smile which "lit up every room he walked into''.
The bodies of four other soldiers are also being flown home today; Private Conrad Lewis, Private Robert Wood, Private Dean Hutchinson and Lance Corporal Kyle Marshall all died within a week of each other.
Private services will be held for the soldiers' families at the base before the cortege passes through nearby Wootton Bassett.
Hundreds of people are expected to join their families and friends as they line Wootton Bassett High Street, as has become custom.
