India said on Friday it had accidentally fired a missile into Pakistan this week because of a "technical malfunction" during routine maintenance, giving its version of events after Pakistan summoned India's envoy to protest.
Military experts have in the past warned of the risk of accidents or miscalculations by the nuclear-armed neighbours, which have fought three wars and engaged in numerous smaller armed clashes, usually over the disputed territory of Kashmir.
Tensions have eased in recent months, and the incident, which may have been the first of its kind, immediately raised questions about safety mechanisms.
"On 9 March 2022, in the course of a routine maintenance, a technical malfunction led to the accidental firing of a missile," the Indian Ministry of Defence said in a three-paragraph statement.
"It is learnt that the missile landed in an area of Pakistan. While the incident is deeply regrettable, it is also a matter of relief that there has been no loss of life due to the accident."

India has ordered inquiryxjmtzyw into launch
The ministry said the government had "taken a serious view and ordered a high-level Court of Enquiry."
Pakistani officials said the missile was unarmed and had crashed near the country's eastern city of Mian Channu, about 500 kilometres from capital Islamabad.
Pakistan's foreign office summoned India's charge d'affaires in Islamabad to lodge a protest over what it called an unprovoked violation of its airspace, saying the incident could have endangered passenger flights and civilian lives.
Pakistan warned India "to be mindful of the unpleasant consequences of such negligence and take effective measures to avoid the recurrence of such violations in future."
Ayesha Siddiqa, an expert on military affairs and South Asian matters, tweeted that "India-Pak should be talking about risk mitigation."
"Both states have remained confident about control of nuclear weapons but what if such accidents happen again & with more serious consequences?"
Concern about India's safetey mechanisms
One senior Pakistani security official told Reuters, on the condition of anonymity, that the incident had raised alarm and could have escalated into a "critical untoward situation."
"The admission that it was a missile was very nonchalant," he said. "What does this say about their safety mechanisms and the technical prowess of very dangerous weapons? The international community needs to have a very close look at this."
The official said it was possibly a BrahMos missile — a nuclear-capable, land-attack cruise missile jointly developed by Russia and India.
According to the U.S.-based Arms Control Association, the missile's range is between 300 kilometres and 500 kilometres, making it capable of hitting Islamabad from a northern Indian launch pad.
The Pakistani official wondered if the incident meant that India had "missiles in ready-to-launch positions and pointed at Pakistan, and that too without any safeguard of a command and control system."
Launch endangered passenger flights: Pakistan official
A Pakistani military spokesperson told a news conference on Thursday evening that a "high-speed flying object" originating from the northern Indian city of Sirsa had crashed in eastern Pakistan.
"The flight path of this object endangered many national and international passenger flights both in Indian and Pakistani airspace as well as human life and property on ground," he said.
A Pakistan air force official said the object, flying at 12 kilometres and three times the speed of sound, had flown 124 kilometres in Pakistani airspace.
Happymon Jacob, a professor of international studies at New Delhi's Jawaharlal Nehru University, said both sides had handled the situation well.
"It gives me great hope that the 2 nuclear weapon states dealt with the missile incident in a mature manner," he wrote on Twitter. "New Delhi should offer to pay compensation for the Pak house that was destroyed."
