The Mumbai killers surfed British websites using BlackBerry mobile phones, according to Indian officials.
The terrorists — at least two of whom are claimed to be from Bradford or Leeds — monitored reports of their murderous spree on sites including the BBC.
The gang looked for web updates and live footage on the net to help them prolong their three-day rampage which left at least 155 dead.
Indian officials said at least five BlackBerry handsets found on the nine dead terrorists showed they had surfed British websites.
