Former Malaysian PM Mahathir, 101, admitted to hospital

Former Malaysian Prime Minister Mahathir Mohamad has been admitted to hospital, his office said on Wednesday, two days after the death of his wife, Siti Hasmah Mohamad Ali.
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.
