Oslo:
Three suspected Al-Qaida members have been arrested in what Norwegian and US officials say was a terrorist plot linked to similar plans in New York and England.
The three men, whose names were not released, had been under surveillance for more than a year. Officials believe they were planning attacks with portable but powerful bombs like the ones at the heart of last year's thwarted suicide attack in the New York City subway.
US Attorney General Eric Holder has called that one of the most serious terrorist plots since 9/11. On Wednesday, prosecutors revealed the existence of a related plot in Manchester, England.
Officials believe the Norway plan was organized by Salah al-Somali, Al-Qaida's former chief of external operations, who was killed in a CIA drone airstrike last year.
