Reykjavik - Iceland's largest bank group Kaupthing was Thursday taken over by the Icelandic Financial Supervisory Authority.
Kaupthing was the third of the North Atlantic nation's major banks to be taken over by the agency under provisions of special legislation adopted late Monday.
Earlier this week the agency took over Landsbanki and Glitnir.
Kaupthing's domestic deposits were "fully guaranteed" and domestic operations were to remain open for business as usual, the agency said adding that the move was "guarantee a functioning domestic banking system."
