An undetermined number of gunmen on Thursday stormed the country’s intelligence service compound in Kabul, a witness at the scene told the Associated Press.

Police Officer Abdul Rahman told the news wire that the gunmen are holed up in a building near the compound from where they are shooting.

He said the shooting was sporadic.

The attack comes one day after a suicide bombing killed 34 in a Shiite area in the city.

No one has claimed responsibility for either attack.
