Iraq raises alarm about foreign IS fighters

US-led coalition members carrying out airstrikes against Islamic State jihadists met in Paris on Tuesday as Iraq's leader pleaded for more support against what he said was an increase in the proportion of foreigners in the group.

Iraqi Prime Minister Haider al-Abadi said the advance of IS represented a "failure" for the global community, upping the stakes ahead of the gathering of about 20ministers from the coalition.

"The flow of foreign fighters is more than before," he told reporters. "There is an international problem; it has to be solved."
