First, there was a pop, like firecrackers, then the world itself seemed to splinter.

Ramjan Rath felt a sharp pain. He looked down, and realised he was on fire.

Rath, whose fuel tanker blew up in a fatal attack on Abu Dhabi claimed by Yemen’s Houthi rebels last month, was standing by his truck filling out forms when the drones hit.

“I saw my vehicle burning right in front of my eyes. There was fire on my feet,” he told The Associated Press on Wednesday from an Indian canteen in Mussafah, the industrial district of Abu Dhabi where the explosion occurred at a nearby state-owned oil facility. “I shook with terror. It wasn’t clear what had happened, it all happened so fast.”

He remembers blood gushing from his leg as he ran for his life. Sirens howled. Hours later, he was in a hospital room.

The 24-year-old had come a long way to the industrial side of the Emirati capital, where Yemen’s brutal war reached for the first-known time on Jan 17. He grew up in a tiny village in the northwestern Indian state of Rajasthan, the youngest son of a farmer.

Rath knew nothing of the years-long civil war that has riven Yemen, killed thousands of civilians and spawned the world’s worst humanitarian disaster. He’d never heard of the Houthis who seized Yemen’s capital, Sanaa, in 2014, and have been battling a Saudi-led coalition that includes the UAE since 2015.

Explainer: What is the war in Yemen?

Like the millions of other low-paid expats who make up the vast foreign labour force powering the UAE’s economy, he had come to the country four years ago for work — the chance to carve out a bit of security for his parents and four older sisters in rural India.

It was a relentless life as a truck driver, working up to 12 hours a day to send money home. But it was a safe one.

Unlike in India, he said, the police were honest, the roads well-paved. He never feared for his life in the federation that is home to oil-rich Abu Dhabi and glitzy Dubai — a refuge in a Middle East mired in conflict and economic collapse.

Yet that changed in a single, violent instant.

“There’s pain, physical and mental. When I sleep at night, or whenever I’m alone, I remember the blast,” Rath said.

He recalls being consumed by guilt in the hospital bed, thinking the inferno must have been his fault, the result of some safety mishap he’d overlooked.

His leg wound required 10 stitches. The ache lingers, causing him to limp. His truck is gone. He can’t work until he heals. He will never tell his family what happened to him, he said. It’s a burden they cannot bear.

But he is alive, and for that he said, he is grateful. Three of his colleagues from India and Pakistan were killed — years of work and accumulated opportunities put to an abrupt end.

One of them was Hardeep Singh. Newly married at 29, he had a bachelor’s degree in computing, enviable skills in the ancient Indian sport of Kabbaddi and dreams of joining his young wife in Canada.

“The house is empty,” Hardeep’s cousin Gagandeep Singh, who called him a brother, said from their village in Indian Punjab. “He was our light, our loveable one.”

Hardeep, known to his family as Appu, was the only child of a widow, saddled with the unyielding obligations of a breadwinner. After his wedding last spring, he returned to work in the UAE as a tanker driver for the Abu Dhabi National Oil Co.

He drove night shifts in the emirate of Sharjah. But that bright Monday morning, a fellow driver in the Mussafah district went on leave. Hardeep was sent to replace him. His family never spoke to him again.

His wife, 21-year-old Kanupriya Kaur, has come undone.

“I have no words,” she said by phone, her voice ragged. “There is no future and my memories are full of pain.”

Darkness has settled over the village of Mehsampur Khurd, where Hardeep’s remains returned last month for a massive memorial. Children who knew him as the “fun one” in the village wept, attendees said.

It has been a shock, that the trail of Yemen’s devastating war has been profoundly felt not only at an Abu Dhabi fuel depot but also an ocean away, in an Indian town home to golden temples.

The Saudi-led coalition has bombarded Yemen for years, drawing international criticism for hitting non-military targets like markets, schools, hospitals and wedding parties. The attack on Abu Dhabi that wounded Rath and killed Hardeep triggered a fierce wave of Saudi and Emirati airstrikes on Yemen.

The deadliest one struck a Houthi-run prison in the northern city of Saada, killing some 90 people. Another strike took the entire country off the internet for days.

Meanwhile, residents of the UAE have witnessed a steady drumbeat of missile and drone interceptions over the past weeks, mostly claimed by the Houthis.

The relentless rhythm of interceptors had been far more familiar to residents of Saudi border towns than the gleaming cities of the UAE, where expats outnumber locals nearly nine to one and beaches are bustling this time of year with tourists soaking up the winter sun.

The puncturing of the illusion of safety, Gagandeep said, is another reason for mourning.

“I can’t accept this. In this war between two countries, our son is lost. Our family is damaged,” he said. “Never have such things happened in the past.”
