In a bid to prevent sectarian murders, British troops erect a corrugated iron anti-sniper screen at Roden Street in Belfast.

The British Army have built a huge, corrugated iron fence outside to separate the Protestant end of Belfast's Roden Street from the nearby Catholic sector.

The idea, hopefully, is to prevent sectarian murders.

For three teenagers the anti-sniper screen has come too late. Sixteen year old Bernard McErlean was killed when a gunmen fired on him and a friend as they stood talking. The following day a gunman opened fire on a group of children walking home from school along Roden Street. Fifteen year old Stephen Robinson was seriously wounded and is in Belfast Royal Victoria Hospital.

In protest, parents refused to send their children to Kelvin Secondary School on Roden Street until something was done to isolate the school from an area known as 'machine gun mansions’. This is an expanse of derelict houses providing cover for snipers. Local parents want the no-man's land completely cleared.

But in the meantime, this screen must act as a shield.

The security forces are blocking off many Belfast streets at random hoping to the element of surprise to prevent snipers setting up planned attacks.

But it's almost impossible to stop a determined killer.

A man was shot on the Shore Road when a gunman stopped him to ask for a light.
