PESHAWAR, Pakistan — Two major airlines suspended their service to Peshawar in northwestern Pakistan on Wednesday, after a gun attack on a crowded airliner here that killed a passenger and raised fears of a concerted militant campaign against the country’s airports.

One of the airlines, Emirates, said in a statement that the attack late Tuesday, in which gunfire ripped through the fuselage of a Pakistan International Airlines flight as it came in to land, had caused it to suspend flights to Peshawar “until further notice.”

The other airline, Etihad Airways, said it had canceled a flight scheduled to land here on Wednesday and would make further decisions based on an assessment of the security situation.

Although there was no claim of responsibility for Tuesday’s attack, most suspicion centered on the Pakistani Taliban, which have threatened to attack foreign airlines in retaliation for a sweeping military drive into their stronghold of North Waziristan that started on June 15.
