The UN Secretary General Ban Ki-moon has unveiled a renewed campaign opposing violence against women.

He says about 70% of women experience some form of physical or sexual violence from men.

Ban Ki-moon said men must teach each other that real men don't violate or oppress women.

The 14 men currently in the network include Spanish PM Jose Luis Rodriguez Zapatero and Archbishop Desmond Tutu.
