New figures on the flow of foreign fighters to Syria and Iraq show the scope of the problem is much bigger than first thought, with would-be militants still finding their way to the battlefront.

For the second time this week, intelligence officials have released updated estimates on the number of foreign fighters, now saying more than 36,500 from at least 120 countries have gone to take part in the fight since the start of the conflict.

That figure includes at least 6,600 Westerners.

The earlier estimates had put the total number of foreign fighters at more than 34,000 from 120 countries, including at least 6,000 Westerners.
