An Israeli delegation of experts landed in Thailand Sunday morning to assist in search and rescue efforts following a major earthquake in the region, the military said.

On Friday, a 7.7 magnitude earthquake and an aftershock measuring 6.4 rocked Myanmar and Thailand, destroying buildings, a bridge and a dam. As of Sunday evening, 1,644 Burmese and 17 Thai citizens were confirmed killed in the quake, with thousands more injured.

The joint military and Defense Ministry team consisting of engineers, doctors and rescue professionals is being led by Col. (res.) Yossi Pinto, the commander of the IDF’s reserve national search-and-rescue unit.

The IDF said the team of 22 experts landed in Bangkok Sunday morning and began to “build an intelligence picture” and give relevant information to Thai authorities.

The quake was the deadliest disaster to hit war-torn Myanmar in years, and prompted the head of the country’s military government to declare a state of emergency, requesting the aid of neighboring countries. China, Russia and India were among the largest nations to respond to the call for help.

In Thailand, the earthquake did significantly less damage, but still rattled buildings in the greater Bangkok area, home to around 17 million people, and other parts of the country. Many places in the north reported damage, but the only casualties were reported in Bangkok.

Of the death toll, 10 were killed in a high rise building that collapsed, while the rest were killed in seven other sites. Authorities in Bangkok said 83 people were unaccounted for.

Rescuers in Bangkok worked Sunday to pluck out survivors trapped when the 30-storey skyscraper that was under construction imploded after the Friday earthquake. Most of the missing are believed to be trapped under the immense pile of debris where the skyscraper once stood.

The shock made 22-year-old survivor, Burmese worker Kyaw Lin Htet, feel like he “lost consciousness,” he told AFP at the site on Sunday.

Sniffer dogs and thermal imaging drones have also been deployed to seek signs of life in the collapsed building, close to the Chatuchak market popular among tourists.
