LONDON - Qatar condemned on Saturday the Islamic State's "barbaric" murder of US journalist James Foley and flatly rejected accusations of giving financial support to the militant group.

Foreign Minister Khaled al-Attiyah's comments came a day after the German government apologised for remarks by a minister accusing Qatar of financing Islamic State militants.

Attiyah described the recent comments as ill-informed.

"Qatar does not support extremist groups, including ISIS, in any way. We are repelled by their views, their violent methods and their ambitions," he said in a statement released in London.

"The vision of extremist groups for the region is one that we have not, nor will ever, support in any way."

Qatar has previously denied supporting Islamist insurgents who have seized wide areas of northern Iraq, northern and eastern Syria.
