'Two dead' in refinery blast

Two people died in an explosion at an oil refinery in Wales, sources said last night.

Fire crews were called to the blaze at Chevron, Pembroke Dock, shortly before 6.30pm.

A spokeswoman for Mid and West Wales Fire Service said fire had completely destroyed a tank. Crews initially put out the blaze, then set about cooling the plant to prevent further explosions.

Milford Haven coastguards reported a "blast large enough to shake the windows" with "black smoke in the air".

Phil Horne, of Milford Haven, said: "I heard a large explosion, turned around and saw a fireball disappearing into the sky."
