Isis in Iraq: Militants 'getting stronger again'

There are growing indications that the Islamic State (IS) group is re-organising in Iraq, two years after losing the last of its territory in the country.

Kurdish and Western intelligence officials have told the BBC that the IS presence in Iraq is a sophisticated insurgency, and IS attacks are increasing.

The militants are now more skilled and more dangerous than al-Qaeda, according to Lahur Talabany, a top Kurdish counter-terrorism official.

"They have better techniques, better tactics and a lot more money at their disposal," he said. "They are able to buy vehicles, weapons, food supplies and equipment. Technologically they're more savvy. It's more difficult to flush them out. So, they are like al-Qaeda on steroids."

The veteran intelligence chief delivered his stark assessment in a London accent - the legacy of years in the UK after his family had to flee from the regime of Saddam Hussein.
