June Steenkamp has delivered the speech her daughter Reeva had planned to give at a South African school on the day she was killed by Oscar Pistorius.

June Steenkamp went back to Reeva's old high school in their home town of Port Elizabeth on Wednesday to talk to students.

She said "I will now carry on where she left off," before reading excerpts of the speech Reeva Steenkamp planned to give at a Johannesburg school on Valentine's Day 2013.

Pistorius fatally shot his girlfriend in the pre-dawn hours of that day. The Olympic athlete was released from jail Monday and moved to house arrest after serving a year of his five-year manslaughter sentence.

Responding to students' questions, June Steenkamp said of Pistorius: "I've got no feelings of revenge."
