S.Africa's president says Eskom power cuts 'most worrying'

South Africa's president Cyril Ramaphosa said on Monday the prospect of more power cuts by utility Eskom were "most worrying".

The cash-strapped company warned of wider controlled power cuts on Monday after six additional generating units unexpectedly went offline.

"That comes as quite a shock. It is reported that there are six units that are down - that is most worrying, most disturbing," said Ramaphosa during a live Twitter broadcast. (Reporting by Tanisha Heiberg; Editing by Mark Potter)
