CANBERRA, June 21 (Xinhua) -- Additional planes are likely to be deployed to search for a missing plane carrying six Australian mining executives near the border of Cameroon and Congo, Australian Foreign Minister said on Monday.
The search has been called off for the night, but will resume at first light, Foreign Minister Stephen Smith said.
"The search provided no conclusive evidence," Smith told ABC Radio.
"We remain very seriously concerned about the welfare of the six Australians."
Smith said the focus of the search was on the border region of Cameroon and Congo.
"There's a distinct possibility that the search effort will be complemented tomorrow with additional helicopters and possibly fixed-wing aircraft."
The chartered aircraft was carrying 11 people, including six Australians, two French, an American and two Britons, most of whom were from Western Australia-based international mining company Sundance Resources Limited, when it disappeared over dense jungle on Saturday.
Sundance Resources said in a statement that most of those on board the flight were from the firm and were visiting the company' s iron ore project in Cameroon and Congo.
