Civil aviation authorities in India are struggling to determine what caused at least 10 pilots to report seeing a "ball of fire" in the air Sunday morning.

Described by several pilots as a "ball of fire, orange in color and scattered," the phenomenon was said to have appeared over the Indian state of Gujarat and has left aircraft officials perplexed at its possible cause, the Sunday Express said.

Air Traffic Control authorities in the New Delhi have been asked to investigate the mysterious incident, but initial inquiries found that no aircraft had been reported missing since it occurred.

Some in India have already speculated that the fireball could be related to Pakistan's recent short-range missile test.

While the neighboring country had informed all regional aircraft pilots of its intent to test the weapon, it did not offer specifics regarding a testing time.

The paper said that any future action on the matter would come after the ATC files its initial investigative report.
