Five opposition parties in Lesotho have formed a new coalition government after snap elections over the weekend failed to produce an outright winner.

The poll was intended to ease tensions after an attempted coup last August.

The All Basotho Convention of outgoing Prime Minister Thomas Thobane came second with 46 seats.

Pakalitha Mosisili's Democratic Congress was narrowly ahead with 47 seats and formed a majority of 61 with other smaller parties.

Announcing the final results, Lesotho's Independent Electoral Commission urged all parties to break away from a cycle of political intolerance.

Last year's power struggle polarised Lesotho's security forces, with the police believed to have sided with Mr Thabane and the army seen as backing his deputy, Mothejoa Metsing who leads the Lesotho Congress for Democracy.

Mr Metsing will remain deputy prime minister as his party has joined the new coalition with its 12 seats in the 120-member parliament.

The army was confined to barracks for the election, which observers said was free and fair. The regional bloc Sadc deployed 475 police officers to provide security.

Mr Mosisili, who served as prime minster from 1998 until 2012, said the mistakes of Mr Thabane would not be repeated by the new government.

Lesotho is completely surrounded by South Africa, which played a key role in mediating last year's political crisis.

It started when Mr Thabane suspended parliament to avoid a motion ousting him as the head of the coalition.

He later fled, saying he was the target of a coup attempt, after the military attacked the police headquarters.
