Lee Kuan Yew, Singapore's founding father and first prime minister, died on Monday at the age of 91 of severe pneumonia.
Lee had been hospitalised at the Singapore General Hospital for severe pneumonia since February 5.
In a statement issued on Monday, the Prime Minister's Office said Lee passed away peacefully at the Singapore General Hospital at 3.18 am (local time), The Straits Times reported.
