A package addressed to Celtic manager Neil Lennon tested positive for a substance which can be used to make explosives, a British court heard today.

An explosion in a remote forest area of Scotland was being investigated by counter-terrorism officers today.

Further details of the fire which crippled a Canadian submarine and claimed the life of one of its seamen, as well as the heroic rescue effort to return the vessel and its crew safely to shore, were expected to emerge today.

It took more than 120 hours but a stricken Canadian submarine was today towed ashore as a royal navy diver told of how a crewman almost drowned in the rescue operation.
