BEIRUT - Lebanon's prime minister has had a heart procedure in a Paris hospital and is expected to be discharged the same day.

Saad Hariri's office says the 48-year-old underwent an hour-long angioplasty procedure, used to treat blocked arteries, on Monday. Hariri's personal physician, Essam Yassin, says the prime minister is well and describes the procedure as a "preventive" measure.

He says Hariri will return to his home in Paris later Monday.

Hariri is the youngest head of state in the region, and has been Lebanon's prime minister for three separate periods since 2009. He is now presiding over his third Cabinet, after being named premier again in February.

His father, Rafik Hariri, a business tycoon who also served as Lebanon's prime minister, was assassinated in 2005.
