Johannesburg - Three mine workers were killed in South Africa's restive platinum belt, a union said Monday, as efforts intensified to break a strike that is now in its fourth month.
The National Union of Mineworkers members were killed while on their way to work, or attacked at their homes, NUM spokesman Livhuwani Mammburu said.
Police said one was hacked to death, a second one was burnt to ashes in his house, while a third was found strangled to death along with his wife in their shack.
Six others were stabbed while walking to work, but survived.
The attacks appeared to bear the hallmarks of inter-union violence, but police could not confirm the motive.
