Harare - Zimbabwean President Robert Mugabe and his wife Grace are not attending a state funeral in Harare after their return from Johannesburg, where the first lady faced calls for prosecution for allegedly assaulting a woman.The president usually leads such high-profile ceremonies, but Zimbabwe's Home Affairs Minister Ignatious Chombo told mourners Sunday that the president won't attend because he "has just returned home".Chombo said one of Zimbabwe's two vice presidents, Phelekezela Mphoko, will instead preside over the funeral for Shuvai Ben Mahofa, a senior member of Zimbabwe's ruling party who died a week ago.The Mugabe couple returned early on Sunday from South Africa, where the president attended a summit of southern African countries. Grace Mugabe was accused of attacking a 20-year-old model with an extension cord in a Johannesburg hotel on August 13.The South African government said on Saturday that it was deciding whether to grant diplomatic immunity to Grace Mugabe at the request of the Zimbabwean government, though there was no immediate comment from South African authorities on Sunday.___10:30 a.m.South African Airways says it will resume flights between South Africa and Zimbabwe after they were blocked by Zimbabwe, which imposed restrictions amid a scandal over an assault claim against the wife of President Robert Mugabe.The announcement by South Africa's state-owned airline came hours after Zimbabwe's state broadcaster reported that Grace Mugabe had returned home with her husband on an Air Zimbabwe flight Sunday morning. There was no immediate comment from the South African government, which had been deliberating whether to grant diplomatic immunity to her at Zimbabwe's request.South African Airways said it has clearance to fly to and from Zimbabwe on Sunday after the lifting of restrictions that were announced on Saturday. Zimbabwe's action followed the grounding of an Air Zimbabwe flight at Johannesburg's main international airport on Friday evening.Both countries say they imposed restrictions because planes did not have a "foreign operator's permit."South African Airways said it has prepared and submitted required documents after the cancellation of flights between Johannesburg, the Zimbabwean capital of Harare and the Zimbabwean city of Victoria Falls.___The wife of Zimbabwean President Robert Mugabe returned home from South Africa on Sunday despite calls that she be prosecuted for allegedly assaulting a young model at a luxury hotel in Johannesburg.A report by Zimbabwean state broadcaster ZBC showed Grace Mugabe greeting government and military officials at the Harare airport after returning on an Air Zimbabwe flight with her husband, who had attended a summit of southern African leaders in Pretoria.The South African government said on Saturday that it was deciding whether to grant diplomatic immunity to Grace Mugabe at the request of the Zimbabwean government, though there was no immediate comment from South African authorities on Sunday. South African police had issued a "red alert" at borders to ensure she didn't leave undetected and said they were waiting for a government decision on the immunity appeal.Gabriella Engels, a 20-year-old model, said Zimbabwe's first lady attacked her on Aug. 13, whipping her with an extension cord that cut her forehead.In reaction to the news that Grace Mugabe had returned to Zimbabwe, a group representing Engels said Sunday they will go to court to challenge the South African government if it is confirmed that immunity was granted to Mugabe."We will take a long term approach on this," said Willie Spies, legal representative at AfriForum, an organization that primarily represents South Africa's white Afrikaner minority."She may be back in Zimbabwe, but it may mean that she will find it very difficult to come back to South Africa in the future," Spies said.The Zimbabwean president's outspoken wife has been criticized for a fiery temper and lavish shopping expeditions, but her rising political profile has some asking whether she is maneuvering to succeed her husband. She recently said that Zimbabwe's ruling party should restore a provision in its constitution stating that one of the party's vice presidents should be a woman, and has publicly challenged her 93-year-old husband to name a successor.President Mugabe is expected to preside at a state funeral for a former minister in Harare on Sunday; it is unclear whether his wife will attend.Amid the scandal over Grace Mugabe, Zimbabwe blocked flights by South Africa's government-owned airline on Saturday after an Air Zimbabwe flight was grounded at Johannesburg's main international airport on the previous evening. Both countries said they imposed restrictions because planes did not have a "foreign operator's permit."
