An ANC ward councillor was assassinated during a meeting in Nelson Mandela Bay on Saturday night, about 50 minutes after a DA candidate was gunned down in Cape Town.

The back-to-back killings unfolded on the first day of SA's final voter registration weekend ahead of the November 4 local government elections.

The Bay's Ward 27 councillor, Sicelo Mleve, representing parts of Zwide and Soweto-on-Sea, was shot dead at his office about 6.50pm.

"It is alleged two unknown armed male suspects stormed the office while a meeting consisting of roughly 10 people was actively underway," police spokesman Captain Majola Nkohli said.
