King Charles is showing his support for Myanmar after a “devastating” earthquake killed over 1,000 people and injured thousands more.

On Saturday, March 29, the monarch, 76, addressed the “people of Myanmar” in a post on his Instagram Stories. The statement came just two days after Buckingham Palace confirmed he was hospitalized due to the side effects of his cancer treatment. (Charles publicly announced his cancer diagnosis in February 2024.)

The King began by stating that he and Queen Camilla “were most dreadfully shocked and saddened to learn of the devastating earthquake in Myanmar, with its tragic loss of life and appalling damage to homes, buildings and livelihoods, not to mention the destruction of sacred pagodas, monasteries and other places of worship.”

“I know that the people of Myanmar continue to endure so much hardship and tragedy in your live, and I have long admired your extraordinary resilience and spirit,” he continued.

“At this most difficult and heartbreaking of times, my wife and I send our deepest possible sympathy to all those who have suffered the profound tragedy of losing their loved ones, their homes and their precious livelihoods,” Charles concluded the statement, singing it, “Charles R.”

King Charles was hospitalized at The London Clinic “following scheduled and ongoing medical treatment for cancer this morning,” Buckingham Palace said in a statement shared with PEOPLE on Thursday, March 27.

He “experienced temporary side effects that required a short period of observation in [the] hospital,” and, as of March 27, was recovering at Clarence House, according to Buckingham Palace.

The King’s events scheduled for that afternoon and the following day were postponed “as a precautionary measure, acting on medical advice,” Buckingham Palace said. Charles was set to visit Birmingham on Friday, March 28, for a series of engagements.

Palace aides did not give further details on King Charles’ particular condition or treatment program, though palace sources said his recovery continues to trend in a positive direction. One royal source described the hospitalization as “the most minor bump in the road that’s very much heading in the right direction.”

King Charles’ message of support for Myanmar comes a day after a 7.7-magnitude earthquake struck the country, resulting in a total of 1,007 known fatalities, the country’s military council confirmed on Saturday, March 29, per BBC News.

A total of 2,389 people have reportedly been injured by the earthquake, as of March 29, while at least 30 remain missing, according to the outlet.
