Seven more held in Britain for terror offences

London - Seven men have been arrested in Britain on suspicion of being involved in terror offences, after weapons were found hidden in a car, police said Friday. A day earlier, six people - one of them a woman - were arrested in London in an operation led by British intelligence agency MI5.

Police said one man from West Yorkshire and six from West Midlands are being questioned on suspicion of the commission, preparation or instigation of acts of terrorism, The Sun reported.

Police said the contents of the car were undergoing forensic analysis and the suspects' homes had been searched.

The arrests followed a routine stop of a vehicle by police on a motorway in South Yorkshire. The car was impounded on suspicion of having no insurance, a police spokesman said.

"Firearms, offensive weapons and other material were later found hidden inside, prompting police to take action to trace and arrest the driver, passenger and others suspected of being involved," he said.

Three men aged 23, 26 and 27 from Sparkhill, Birmingham, a 22-year-old from Alum Rock, Birmingham, a 24-year-old from Moseley area of the city, and a 22-year-old from Smethwick, West Midlands, were arrested.

A 43-year old man from Kirklees, West Yorkshire, was also detained.

On Thursday, six men and a woman, suspected to be involved in terrorism offences were arrested in London.

The arrests were related to a possible plot involving Islamist extremists, with potential British targets. However, they were not linked to the Olympics or Paralympics, BBC reported.

Britain's terror threat level is still "substantial", which means a terrorist attack is a "strong possibility", police said.

There are two higher levels - "severe", meaning an attack is "highly likely", and "critical", meaning an attack is "expected imminently", BBC said.
