Guilty of helping IS

A US soldier based in Hawaii has pleaded guilty to trying to help Islamic State.

Sergeant 1st Class Ikaika Kang, 35, told a judge he provided secret military information, a drone meant to track US troops and other support to purported members of the terrorist organisation.

Kang pleaded guilty to all four charges that were laid against him.

He is expected to be jailed for 25 years as part of a plea agreement when he is sentenced for the offences on December 10.
