The wife of Lesotho Prime Minister Tom Thabane was shot dead late on Wednesday, just hours after her husband’s inauguration, raising fear of another wave of political violence in the country.

Police spokesperson Clifford Molefe said Lipolelo Thabane, 58, was travelling home with a friend when both women where shot by an unknown assailant in the town of Masana, just outside the capital, Maseru.

Molefe said Lipolelo died on the scene while her friend was taken to a nearby hospital. He said the motive of the shooting was unknown and investigations were ongoing.

Lesotho, which has been on a political knife-edge since an attempted coup in 2014, held elections last week, the third in five years, after then-prime minister Pakalitha Mosisili lost a no-confidence vote in March.

Thabane’s All Basotho Convention won 48 parliamentary seats, compared with 30 won by Mosisili’s Democratic Congress.

Thabane and Lipolelo had been living separately since 2012 after Thabane filed for a divorce, which had yet to be granted by the courts.

Thabane’s office could not be reached for comment. (Reuters)
