Bolivia's interim government and lawmakers from the party of unseated leader Evo Morales struck a deal late on Thursday to pursue new elections, potentially helping resolve the South American country's political crisis.

In a late night session of the Bolivian Senate, the chamber's President, a member of Morales' Movement for Socialism (MAS) party, said there was agreement to work towards new elections after weeks of protests and violence that led to leftist leader Morales resigning under pressure last Sunday.

"Today is an historic day where we have been able to agree between opposition and government with the sole objective to make new elections as soon as possible, to pacify our country and above all to defend democracy," said Monica Eva Copa Murga, who had earlier been confirmed in the her role.
