ISLAMABAD — Pakistan says it is deeply concerned over what it said was an “unauthorized” American raid that killed Osama bin Laden.

The government statement today said the raid should not serve as a precedent for future U.S. actions in the country.

Washington says it did not inform Islamabad about Monday’s helicopter attack on bin Laden in a house deep inside Pakistani territory for security reasons.

Domestic critics have accused the government of allowing Washington to violate the country’s sovereignty.

Islamabad is also angered at international suspicions that it had been sheltering bin Laden.
