Amateur video 'shows ISIS fighters near Iraq refinery'

The Iraqi army says it has beaten off Islamist-led militants attacking the country's biggest oil refinery amid reports that most of it is in militant hands.

An official told Reuters the militants had occupied 75% of the Baiji refinery, 210km (130 miles) north of Baghdad.

Meanwhile, unverified amateur video has emerged which purports to show ISIS fighters near the refinery - although it is not visible in any shots.
