South Africa apologises for summit break-ins

South African officials have expressed regret after a Swiss delegate to the UN summit was assaulted in her hotel room and another was robbed while she slept.

Intelligence Minister Lindiwe Sisulu called the incidents "regretful".

No arrests have been made, but an investigation is underway.

According to authorities, the robber apparently entered one sleeping delegate's room at a guest house and stole a purse, cash and a mobile phone. He then entered another room and turned on a light, waking the occupant up.

The robber fired one shot before fleeing, but the woman, identified as Rosmarie Bar, was not injured.

Ms Bar, coordinator of development policies for a Swiss aid group, has returned home.

It was not known how much cash was stolen.

The guest house is about eight miles from the main conference site. Swiss officials said security has been increased.

South African officials have called out the army and special forces to help police combat Johannesburg's rampant crime and violence during the summit.
