N Korea extends condolences to Singapore over Lee Kuan Yew's death

North Korea has sent their condolences to Singapore on Tuesday over the death of former prime minister Lee Kuan Yew, reported news agency Yonhap.

Premier Pak Pong-ju called him a "close friend" of the communist country, said (North) Korean Central News Agency (KCNA) in a brief English report.

The message from Pak was sent to Prime Minister Lee Hsien Loong and "expressed the deepest condolences to the prime minister and the bereaved families".

"Lee Kuan Yew, founder of the Republic of Singapore and a close friend of Korean people, passed away to their sorrow," noted KCNA in the report.

The two countries forged diplomatic relations in 1975.

Lee died on Monday at the age of 91.
