India says it accidentally fired a missile into Pakistan on Wednesday, blaming the incident on a "technical malfunction" during routine maintenance.
Delhi said it was "deeply regrettable" and expressed relief no one was killed.
Pakistan's military said a "high-speed flying object" had crashed near the eastern city of Mian Channu and its flight path had endangered passenger flights.
Both countries have nuclear weapons.
In a statement, India's defence ministry said: "On 9 March 2022, in the course of routine maintenance, a technical malfunction led to the accidental firing of a missile. The Government of India has taken a serious view and ordered a high-level Court of Enquiry."
Islamabad warned Delhi to "be mindful of the unpleasant consequences of such negligence" and to avoid a repeat.
