POLICE were early today investigating an explosion at an oil terminal

at North Shields, Tyne and Wear.

The blast came less than 24 hours after an explosion and fire at a gas

holder in nearby Gateshead.

Police, forensic, and bomb squad officers were still searching for

clues to the cause of that blast, with no trace of evidence that would

point to a bomb.

Details were scarce about the North Shields incident. There was no

fire at the site and no reported casualties, Tyneside fire service said.

Firemen were called to the Esso terminal at 11.19pm.

The terminal was also the target of a bomb blast in April, on the day

before the IRA's massive bomb attack on the City of London.

On that occasion, a device holed a storage tank, but caused no

injuries. Police said they were confident it was the work of the IRA.

The explosion and fire at the gas depot in Gateshead had all the

hallmarks of a terrorist attack.

But with no claim of responsibility for the blast just before midnight

on Tuesday and no trace of a bomb, police are keeping an open mind

publicly about its cause.

But Detective Chief Superintendent Barry Stewart, head of Northumbria

CID, said: ''We are treating the incident as a crime but I would not

like to say what the nature of the crime is at this stage.''

Yesterday's incident happened only a mile from the Metrocentre

shopping complex where on May 9 last year several IRA incendiary devices

were planted in stores, some going off but causing only minimal damage.

Residents of 250 houses near the gas depot were evacuated to community

centres. Pensioners, some in their 80s, were shaken by a loud explosion

and saw 30ft flames burst from the storage tank.

About 100 firefighters tackled the blaze whose heat damaged windows of

nearby houses. However, the half-full, 1.7 million cubic foot capacity

storage tank was not badly damaged.

British Gas Northern ruled out any chance of the explosion being an

accident. A spokesman said: ''We don't believe it was caused by a

normal, operational failure.''
