Former Malaysian PM Mahathir, 101, admitted to hospital for observation

Mahathir, 101, was admitted to the National Heart Institute in Kuala Lumpur on Tuesday night for observation, ⁠though the reason for his admission was unclear pending an official diagnosis, his aide Sufi Yusoff said.

Mahathir, who led the Southeast Asian nation for more than two decades in two stints, has a history of heart problems and has undergone bypass surgeries. 

He has been hospitalised ‌repeatedly ⁠in recent years, most recently in January for a hip fracture after a fall.

His wife Siti Hasmah, a medical doctor and public health advocate to ⁠whom he was married for 70 years, died on Monday at the age of 100.

Mahathir was visibly affected ⁠by her death, tearfully telling the country's former king that he "didn't expect her to die ⁠today," according to video taken during her funeral and posted on his social media accounts.
