Lawyer Elvino Dias and official Paulo Guambe shot as their party plans a national strike over disputed election

Attackers killed a Mozambique opposition lawyer and a party official after firing rounds at a car in which they were travelling, ratcheting up tensions before protests against a disputed election result, the EU and rights groups have said.

Mozambique’s new opposition Podemos party and its presidential candidate, Venâncio Mondlane, have rejected provisional results showing a probable win for Frelimo, the party that has ruled Mozambique for half a century. They have called for a nationwide strike on Monday.
