CNN reported that Kim's condition is being monitored by U.S. intelligence officials after the recent cardiovascular operation.

The report came after a Seoul-based internet news outlet said that Kim has been receiving medical treatment at a villa in the resort county of Hyangsan, outside of Pyongyang, after the surgery.

Speculation abound after Kim skipped the annual celebration of his grandfather's birthday on April 15. Some observers said he did so due to coronavirus concerns.

Kim last appeared in North Korean state media on April 11.
