Nazrul Islam, personal secretary of the party chief, told UNB about the blocks on Wednesday night.

He said that Shafiqur has been diagnosed with three major heart blocks and is currently undergoing treatment at the United Hospital in the capital.

Meanwhile, in a Facebook post, Hafez Rashedul Islam, former central president of Islami Chhatra Shibir and current Ameer of Jamaat’s Dhanmondi Thana unit,  wrote although  Shafiqur’s family and personal physician recommended that the surgery be performed abroad, he opted to have the procedure done in a hospital in the country.

He completed his speech while seated and was later taken to hospital for medical examination.

Since then, he has been undergoing a series of health check-ups, which led to the diagnosis.
