Kuwait City, July 23 (IANS) Kuwaiti Emir Sheikh Sabah Al-Ahmad Al-Jaber Al-Sabah will leave for the US on Thursday to complete medical treatment following his recent surgery, state-media reported.

The Kuwaiti emir was admitted to a hospital on July 18 for a medical checkup and had a "successful" surgery a day later, the Kuwait News Agency quoted Minister of Amiri Diwan Sheikh Ali Jarrah Al-Sabah as saying on Wednesday.

Kuwaiti Crown Prince Sheikh Nawaf Al-Ahmad Al-Jaber Al-Sabah will "temporarily carry out some of his duties", Xinhua news agency reported citing KUNA as saying.

Last summer, the Emir was reported to have suffered a health "setback" while in Kuwait.

Sheikh Sabah has been credited with shaping the Gulf nation's foreign policy and spent decades as foreign minister before becoming emir in 2006.
