Terrifying footage has emerged of a gigantic car bomb exploding in Iraq, with its massive shockwave clearly captured.

At the start of the clip, seemingly shot on a mobile phone, a group of armed men can be seen standing by the side of a road.

There is then a massive explosion that sends the filmmaker diving for cover behind a barrier as the ground shakes.

A split second after the bomb goes off a huge shockwave rushes outwards.

The clip was originally uploaded to the Facebook page of the Popular Mobilisation Forces, a coalition of fighters battle Isis.

It said that the bomb went off in the north of Samarra, which lies about 80 miles to the north-west of Baghdad.

It’s not clear if there were any deaths or injuries from the explosion.

The footage emerged as Isis claimed responsibility for a suicide blast and a roadside bombing on Friday that targeted Shiites in Baghdad, killing a total of 26 people and wounding dozens.

The attacks came as Iraqi Kurdish militias, backed by U.S. airstrikes, seized the town of Sinjar from Isis in a major blow to the extremists. Following its blitz last year, Isis - which splintered off from Iraq's al-Qaida branch - now holds about a third of Iraq and neighbouring Syria in its self-declared caliphate.

In the aftermath it's clear that some were left shaken by the bomb

The suicide bomber struck a memorial service held for a Shiite militia fighter killed in battle against Isis in the Iraqi capital's southwestern suburb of Hay al-Amal, a police official told The Associated Press. That explosion killed 21 people and wounded at least 46, he said.

The militia fighter was killed in battle against the militant group in Iraq's western Anbar province, the official added.

Also Friday in Baghdad, a roadside bomb detonated at a Shiite shrine in Sadr City, killing at least five people and wounding 15, police officials said. Hospital officials confirmed the casualty figures. All officials spoke on condition of anonymity as they were not authorized to talk to reporters.

Since the emergence of Isis extremists, Baghdad has seen near-daily attacks, with roadside bombs, suicide blasts and assassinations targeting Iraqi forces and government officials, with significant casualties among the civilian population.

The violence has killed hundreds and displaced tens of thousands of Iraqis.

Shiite militia fighters answered a call to arms last year after the country's highest Shiite religious authority, Ayatollah Ali al-Sisani, called on Iraqi men to defend the country. The militias, which later formed umbrella paramilitary force the Popular Mobilization Forces, have been an integral part in the battle against the Islamic State group, supporting Iraqi forces in battles in Salahuddin, Anbar and Baghdad provinces.
