LAHORE/KARACHI/ISLAMABAD: As Musfira, a seemingly healthy one-and-a-half-year-old girl, plays with the toys on the floor, her mother Salsabeel Safi, 22, tries to catch her attention with a wooden toy car that has watermelon wheels.

It’s a typical picture of a mother playing with her daughter, except they are facing a medical crisis after India canceled most valid visas, including medical visas, issued to Pakistani nationals amid rising tensions between the two nuclear rivals.

“We had applied for an Indian visa in December. It has been four months now, but we didn’t get a visa. Because of the Pakistan-Indian situation our visa has been stopped,” said Safi.

Musfira has no veins between her heart and lungs and her arteries are so severely constricted that she has very poor blood circulation, said Safi. Her heart also has a hole in it. As a result, Musfira’s mother says she frequently turns blue and has to be hospitalized due to insufficient oxygen in her body.

The family has sought help at several hospitals in Pakistan, but was told that the little girl’s condition could not be treated in the country. At the suggestion of doctors they consulted in Pakistan, the family decided to seek surgical intervention in India.

While treatment options for Musfira’s condition are available in other countries, the family felt India was the best choice due to its proximity and affordable health care. They could even travel there by car.

Once she learnt that treatment would cost an estimated $10,000, Safi, who’s a content creator on social media, started raising funds online.

Last December, Musfira’s family applied for their visas after an Indian hospital invited them to seek treatment there, but they were soundly rejected.

“Her condition is deteriorating,” said Safi.

Many Pakistani families have found themselves in the same predicament as India and Pakistan continue to hold a fragile US-brokered ceasefire after nearly three weeks of escalating tensions that took South Asia to the brink of war.

Mohammad Imran and his wife, Nabeela Raaz, an Indian national, traveled from Karachi to India with their 17-year-old son, Mohammad Ayan, who suffers from a spine injury on March 27. When India revoked most visas for Pakistani nationals in late April, they returned to Pakistan on April 27 before Ayan could receive any treatment. Ayan’s mother was not allowed to accompany them back to Pakistan.

“My son keeps crying,” said Imran. “Even I cry at times when my son says, ‘Please call mama here’. I can’t see her coming here anytime soon.”

In Islamabad, Shahid Ali said his two children who suffer from heart disease were forced to return to Pakistan without getting the surgery they desperately needed.

“The Pahalgam incident took place and the Indian government ordered the cancelation of visas in 24 hours,” said Ali.

On April 22, 26 men were killed in an attack targeting Hindus in Pahalgam in Indian-administered Kashmir. It was the worst attack on civilians in India since the 2008 Mumbai shootings.

The next day, India pulled out of the 1960 Indus Water Treaty regulating the sharing of water from the river and its tributaries with Pakistan.

India also identified two of the three suspected militants in the Pahalgam attack as Pakistanis, although Islamabad denied any role.

On May 7, India launched attacks on what it said were “terrorist camps” in Pakistan, including Azad Kashmir.

Strikes and counter-strikes and a slew of tit-for-tat reprisals followed before US diplomacy and pressure helped the two nations agree to a “full and immediate ceasefire” on May 10.

Despite the truce, punitive measures announced by India, such as trade suspension and visa cancelations, remain in place, according to Indian government sources who spoke to Reuters.

For the families of these Pakistani children, some of whom are hanging on by the thinnest thread, a solution to the latest chaos cannot come sooner.

“We want India and Pakistan to resolve issues between them so that Musfira and several other children like her, whose treatment is due in India, can get visas and get treatment there,” said Musfira’s uncle, Zulkifl Haroon. “So that their lives can be saved.”
