South African prosecutors say they will take court action in order to secure a longer prison sentence for Olympic athlete Oscar Pistorius.
He was jailed for six years earlier this month for murdering his girlfriend Reeva Steenkamp in 2013.
Prosecutors argue that Pistorius' sentence is inappropriate for the crime of murder and "shockingly too lenient".
