A former Zambian cabinet minister was shot dead during a security operation at the home of opposition leader Brian Mundubile, police said Wednesday, days after President Hakainde Hichilema won a second term amid opposition claims of irregularities and intimidation.

Police said Mutotwe Kafwaya, 49, was killed during a joint security operation at Mundubile’s residence, a day after the August 13 presidential election.

According to police, security forces encountered gunfire and resistance from unidentified individuals during the raid and returned fire. An unidentified man was fatally wounded and a firearm was recovered.

Authorities later confirmed the dead man was Kafwaya, a former cabinet minister and opposition parliamentarian.
