Terror groups at an ‘unprecedented scale’

A UN report says the world is facing a challenge of foreign fighters in terror groups on an "unprecedented scale", with about 15,000 in Syria and Iraq alone.

The report by a panel of experts monitoring al Qaeda and the Taliban has been submitted to the UN Security Council.

“Numbers since 2010 are now many times the size of the cumulative numbers of foreign terrorist fighters between 1990 and 2010 — and are growing,” the report says.
