ISLAMABAD (AP) — Pakistan’s imprisoned former Prime Minister Imran Khan is in good health after undergoing a medical procedure for an eye ailment at a government hospital, an official said Thursday. Khan remains widely popular in Pakistan, and the government’s acknowledgment of his hospital visit has raised concerns about his treatment and medical condition. “He is in good health,” Information Minister Attaullah Tarar told the private Geo News television channel. Suhail Afridi, a chief minister in the northwest Pakistan and a prominent member of the Pakistan Tehreek-e-Insaf party, said that he was trying to meet with Khan in prison. Authorities recently restricted meetings between Khan and his family after relatives publicly conveyed political messages urging supporters to stage rallies against the government of Prime Minister Shehbaz Sharif.
