Pakistani PM to undergo heart surgery in London
Pakistani Prime Minister Nawaz Sharif will undergo open heart surgery in London on Tuesday, his family and media said.
It will be Sharif's second heart operation in five years.
Sharif's daughter, Maryam Nawaz Sharif, said on her official Twitter account that the surgery would be for "perforation of the heart", a complication from an earlier procedure in 2011.
