South African President Jacob Zuma and his Zimbabwean counterpart, Robert Mugabe, are seen at the AU summit in Addis Ababa earlier this year.

Johannesburg - President Jacob Zuma on Sunday congratulated Robert Mugabe on his re-election as president of Zimbabwe.

"President Zuma urges all political parties in Zimbabwe to accept the outcome of the elections as election observers reported it to be an expression of the will of the people.

" (He) also encourages the people of Zimbabwe to seize this opportunity to collectively contribute towards building their country driven by a common desire for peace, stability and prosperity."
