South Africa’s President Cyril Ramaphosa was jeered and whistled at on Saturday during his speech at Zimbabwe ex-leader Robert Mugabe’s funeral before he apologised for recent xenophobic attacks. At least 12 people have been killed this month in a surge in violence and mob attacks against foreign-owned businesses in and around Johannesburg, South Africa’s largest city. A wave of jeers, boos and whistles interrupted Ramaphosa at the Harare national stadium as he started his eulogy at the state funeral for Mugabe, who died age 95 last week.
