We want to redirect our youths. They should know that the country was fought for," Mugabe was quoted as saying.This was the first time that the president spoke about his sons, following his wife Grace's alleged assault of a young model Gabriella Engels at a Johannesburg hotel.Grace reportedly used an extension cord to beat Engels while her bodyguards looked on after she allegedly found her (Engels) with Bellarmine Chatunga at a hotel in the leafy suburb of Sandton.Robert Jnr and Bellarmine Chatunga, who were learning in South Africa were known for notoriety and lavish lifestyles. The duo was recently kicked out of an apartment block in the leafy Sandton after they reportedly engaged in "unacceptable behaviour" that left a security officer at the block with a broken leg and arm, prompting Grace to fly to South Africa to organise alternative accommodation for them.
