BANGKOK, Thailand (Reuters) — Aid groups in the worst-hit areas of Myanmar said there was an urgent need for shelter, food and water after an earthquake that killed more than 2,700 people last week, but said the country’s civil war could prevent help reaching those in need.

The death toll had reached 2,719 and is expected to rise to more than 3,000, Min Aung Hlaing, the head of Myanmar’s military junta, said in a televised address on Tuesday. He said 4,521 people were injured, and 441 were missing.

The 7.7 magnitude quake, which hit around lunchtime on Friday, was the strongest to hit the Southeast Asian country in more than a century, toppling ancient pagodas and modern buildings alike.

In neighboring Thailand, rescuers pressed on searching for life in the rubble of a collapsed unfinished skyscraper in the capital Bangkok, but acknowledged time was against them.

In Myanmar’s Mandalay area, 50 children and two teachers were killed when their preschool collapsed, the United Nations Office for the Coordination of Humanitarian Affairs said.

“In the hardest-hit areas… communities struggle to meet their basic needs, such as access to clean water and sanitation, while emergency teams work tirelessly to locate survivors and provide life-saving aid,” the UN body said in a report.

The International Rescue Committee (IRC) said shelter, food, water and medical help were all needed in places such as Mandalay, near the epicenter of the quake.

“Having lived through the terror of the earthquake, people now fear aftershocks and are sleeping outside on roads or in open fields,” an IRC worker in Mandalay said in a report.

The civil war in Myanmar, where the junta seized power in a coup in 2021, has complicated efforts to reach those injured and made homeless by the Southeast Asian nation’s biggest quake in a century.

Amnesty International said the junta needed to allow aid to reach areas of the country not under its control. Rebel groups say the junta has conducted airstrikes after the quake.

“Myanmar’s military has a longstanding practice of denying aid to areas where groups who resist it are active,” Amnesty’s Myanmar researcher Joe Freeman said.

“It must immediately allow unimpeded access to all humanitarian organizations and remove administrative barriers delaying needs assessments,” said Freeman.

The junta’s tight control over communication networks and the damage to roads, bridges and other infrastructure caused by the quakes have intensified the challenges for aid workers.

Thai officials said a meeting of regional leaders in Bangkok later this week would go ahead as planned, although the junta’s Min Aung Hlaing may attend by teleconference.

Before the quake struck, sources said the junta chief had been expected to make a rare foreign trip to attend the summit in Bangkok on April 3-4.

In Bangkok, rescuers were still scouring the ruins of an unfinished skyscraper that collapsed for any signs of life, but aware that as four days had passed since the quake, the odds of finding survivors lengthened.

“There are about 70 bodies underneath … and we hope by some miracle one or two are still alive,” volunteer rescue leader Bin Bunluerit said at the building site.

Bangkok Deputy Governor Tavida Kamolvej said six human-shaped figures had been detected by scanners, but there was no movement or vital signs. Local and international experts were now working out how to safely reach them, she said.

Search and rescue efforts continued at the site, supported by multinational teams, including personnel from the US and Israel.

Israel’s delegation, which comprises some two dozen experts from the Defense Ministry and the National Rescue Unit of the IDF’s Home Front Command, landed in Bangkok on Sunday, the Israeli military said.

Meanwhile, family and friends of people caught in the quake said they feared the worst.

“The rescue teams are doing their best. I can see that,” said 19-year-old Artithap Lalod, who was waiting for news of his brother.

“However it turns out, that’s how it has to be. We just have to accept that things will be the way they are,” he said.

Thirteen deaths have been confirmed at the building site, with 74 people still missing. Thailand’s national death toll from the quake stands at 20.

Initial tests showed that some steel samples collected from the site of the collapsed building were substandard, Thai industry ministry officials said. The government has launched an investigation into the cause of the collapse.
