Multiple major airlines are avoiding flying over Pakistan as relations with neighbor India crater in the wake of a recent tourist massacre, the latest geopolitical flashpoint to disrupt global travel.

The airline is “adapting its flight schedule and flight plans to and from certain destinations,” the French flag carrier said, adding some routes will require longer flight times.

“Air France is constantly monitoring developments in the geopolitical situation of the territories served and overflown by its aircraft in order to ensure the highest level of flight safety and security,” Air France said.

Germany’s flag carrier Lufthansa also confirmed to Reuters that it was “avoiding Pakistani airspace until further notice.”

The travel disruptions come two weeks after militants massacred 26 civilians, mostly tourists, in the mountainous town of Pahalgam in Indian-administered Kashmir, a rampage that has sparked widespread outrage.

India was quick to place blame for the assault on Pakistan, which it has long accused of harboring militant groups. Pakistan denied involvement, and tensions have mounted since with a series of escalatory tit-for-tat moves between the two neighbors.

Both sides had already closed their airspaces to each other’s aircraft since the attack, but the increased tensions are now impacting other international airlines and will likely cost them as they burn extra fuel taking longer routes.

Airlines have already had to be cautious about other key flashpoints in recent years, including the Middle East and areas close to the Ukraine-Russia front lines.

Flight-tracking data showed some flights of British Airways, Swiss International Air Lines and Emirates traveling over the Arabian Sea and then turning north toward Delhi in order to avoid Pakistani airspace, Reuters reported.

Kashmir, one of the world’s most dangerous flashpoints, is controlled in part by India and Pakistan but both countries claim it in its entirety. The two nuclear-armed rivals have fought three wars over the mountainous territory that is now divided by a de-facto border called the Line of Control (LOC) since their independence from Britain nearly 80 years ago.

In the wake of the tourist massacre, India and Pakistan have been flexing their military muscle, putting both countries on edge.

Pakistan on Monday carried out a second missile test in three days, Reuters reported.

The Pakistani army said the missile tested was a Fatah series surface-to-surface missile with a range of 120 kilometers (75 miles), according to Reuters. It came two days after the successful launch of a surface-to-surface ballistic missile.

India has also ordered all its states and union territories to carry out mock security drills on Wednesday.

It comes days after India’s navy said it had carried out test missile strikes to “revalidate and demonstrate readiness of platforms, systems and crew for long range precision offensive strike.”

Tensions have ramped up despite the United States and China – two major global players – urging restraint.

The United Nations Secretary-General, Antonio Guterres, on Monday also urged both India and Pakistan to “avoid a military confrontation that could easily spin out of control.”

“Make no mistake: A military solution is no solution,” he added.

All mobile phone signals will be deactivated in the Vatican on Wednesday ahead of the highly secretive conclave to elect the next pope, Italian state media reported.

The Vatican also plans to use signal jammers around the Sistine Chapel to prevent electronic surveillance or communication outside the conclave that will see 133 cardinals vote on who will succeed Pope Francis and lead the world’s 1.4 billion Catholics, Italian news agency ANSA reported.

Phone signal will be cut off at 3 p.m. local time (9 a.m. ET) on Wednesday, an hour and a half before the cardinals are scheduled to proceed to the Sistine Chapel to begin the papal conclave, Italian state broadcaster RAI reported on Monday.

All 133 cardinals who will vote to elect Francis’ successor have already arrived in Rome, the Vatican confirmed on Monday.

For centuries, the leader of the Catholic Church has been chosen in a highly secretive gathering known as “conclave,” meaning “with key” in Latin – a nod to how cardinals used to be locked in until a new pope was selected. Cardinals tasked with picking the next pontiff follow an elaborate process with roots in the Middle Ages.

The cardinals will have to give up their phones and all electronic devices starting Tuesday and will only get their devices back once the conclave has ended, a Vatican spokesman said.

The cardinals will all be shut in the Sistine Chapel and locked away from the outside world from Wednesday. All of the cardinals taking part in the conclave will be in complete isolation and will take a vow to observe “absolute and perpetual secrecy”.

The signal deactivation will not affect St Peter’s Square, where the public often gather, according to the spokesman. But security has been ramped up throughout St Peter’s Square, with checkpoints at the entrances and the deployment of metal detectors and anti-drone systems at the public space, according to news outlet Corriere della Sera.

The Sistine Chapel is placed under total lockdown during conclave to guarantee complete secrecy. In 2013, during the conclave that elected Francis, signal blockers were also installed to prevent any calls, texts, or internet access.

Even the electricians, plumbers and elevator operators who will keep the Vatican running during the conclave will commit themselves to secrecy.

“They all take an oath and will be in full-time service, staying overnight in the Vatican, without having contact with their families,” according to a statement from the Vatican City State Governorate.

Japan’s Emperor Emeritus Akihito will be admitted to hospital for heart tests on Tuesday, public broadcaster NHK reported, citing the Imperial Household Agency.

Akihito, 91, who is retired, is the father of Emperor Naruhito. He abdicated from the Chrysanthemum Throne in 2019, seven years after he had heart bypass surgery.

The former emperor will undergo tests at the University of Tokyo Hospital after signs of myocardial ischemia were found during a regular checkup last month, NHK reported, citing the Imperial Household Agency. The condition reduces blood flow to the heart muscle.

Akihito, who ascended to the throne after his father, Hirohito, died in 1989, became the first Japanese monarch in 200 years to abdicate his post.

He cited health reasons for standing down, having undergone heart surgery and been treated for prostate cancer in the years preceding his abdication.

A man prepared to break with tradition, Akihito was the first Japanese emperor to marry a commoner, speak to his subjects live on television, and be hands-on in raising his children.

The emperor is a ceremonial but revered figure in Japan’s constitutional monarchy. It is the oldest hereditary monarchy in the world, dating back 14 centuries.
