KABUL: Afghanistan's intelligence agency on Thursday said it had prevented a large terrorist attack in the capital, arresting a Pakistani national driving a truck packed with explosives in Kabul.

The agency said in a statement that the man was arrested Thursday on a major road in the east of the city. It said the man was going to use the truck bomb in a suicide attack.

The agency did not say what the suspected target was. It said it would release more details as they became available.

The arrest comes a day after a suicide attack on the same road killed seven people. In that attack one militant detonated his car bomb outside a compound where foreigners live, while two other attackers fought their way inside before being killed.
