Pakistani fighter jets flew low near major cities Monday amid tensions with India triggered by last month's terror attacks on Mumbai. The air force declined to comment on the flights but issued a statement saying that “in view of the current environment, the Pakistan Air Force has enhanced its vigilance.” The apparent exercises briefly delayed two Pakistan International Airlines flights, said a spokesman for the airline. “Two of our flights were delayed for some time because the PAF was conducting some exercises but now everything is back on normal,” said Muhammad Latif, a spokesman for Pakistan International Airlines, referring to the air force (PAF). Several jets were seen flying close to Lahore and Islamabad, alarming some residents, Latif said, while dismissing television news channel reports of a high alert at Pakistani airports. Last weekend, Pakistan said Indian jets violated its airspace in two parts of the country, but were chased back over the border. New Delhi said there was no violation.
