US diplomacy on Tuesday condemned what it called an “army attack” by Myanmar against a camp for internally displaced people, killing dozens of civilians.

At least 29 people, including women and children, were killed in artillery shelling near the border with China, which sources in the region attributed to military junta forces.

“We are deeply concerned about reports of an attack by the Burmese military against a camp of internally displaced people (…) in Kachin State on October 9,” said a State Department statement signed by spokesman Matthew Miller and using its historical name Asian country, which changed during a previous military regime.

“We strongly condemn the continued attacks by the military regime, which have claimed thousands of lives since the February 2021 coup and continue to exacerbate the most serious humanitarian crisis across the region,” the US State Department press release added.

The attack is among the deadliest against civilians since the military overthrew the democratically elected government of Aung San Suu Kyi on February 1, 2021, triggering a civil war with a resistance movement and armed separatist groups across Myanmar.

According to converging sources, the camp, about 5 kilometers from a Kachin Independence Army (KLA) rebel base in Laiza commune, was hit by artillery.

In and around Laiza live many civilians who were displaced during the hostilities. The UN estimates that the displaced people of the conflict in Myanmar exceed one million.

The shadow government of national unity and the British embassy in Yangon also blamed the army for the shelling of the Kachin camp. The first spoke of a “war crime and crime against humanity” by the junta.

A spokesman for the military regime denied that the armed forces were responsible for the carnage and claimed that the tragedy might have been due to the rebels’ stockpiled ammunition, without going into details.

At least 4,100 people have been killed in the wave of murderous repression that followed the military coup in Myanmar, according to human rights figures.
