Jalalabad (Afghanistan) (AFP) – Afghan authorities were searching Tuesday for about 270 inmates — most of them Islamic State fighters — who remained on the loose after escaping during a deadly prison raid.

At least 29 people were killed when Islamic State (IS) gunmen attacked the facility in Jalalabad on Sunday, with fierce fighting lasting until Monday afternoon.

More than 1,300 inmates tried to escape, a senior Afghan security official told AFP on condition of anonymity, but most were either swiftly re-arrested or surrendered when surrounded by security forces.

But some 270 prisoners are “still on the loose”, the official said.

“Most of those who escaped are from ISKP,” he said, referring to IS’s Afghan branch, known as the Islamic State in Khorasan Province.

They included militants responsible for several bloody attacks, a second security official told AFP.

Nangarhar provincial governor’s spokesman Attaullah Khogyani confirmed many prisoners were still missing, but couldn’t say how many were IS members.

The brazen prison raid came a day after Afghanistan’s intelligence agency announced the killing of a top IS commander near Jalalabad.

Nangarhar province, where IS got its first foothold in Afghanistan, has seen repeated attacks by the group, including a suicide bomb that killed 32 mourners at a funeral in May.

– Calm shattered –

The attacks have continued even though officials last year claimed IS had been defeated in Nangarhar.

“A large number of their leadership was arrested or killed … so it (the prison raid) was some sort of revenge to free some of their comrades,” a senior Afghan security official said.

The prison raid shattered the relative calm of the final day of a three-day ceasefire between the Taliban and Afghan forces.

IS was not part of the truce.

The Afghan government still attempted to link the raid to the Taliban, which it said had violated the ceasefire 38 times.

Acting Interior Minister Massoud Andrabi said on Twitter that IS’s new head in Afghanistan, Shahab Al-Mahajir, was a member of the Haqqani network, considered a Taliban offshoot.

Washington has branded the Haqqani network, accused of carrying out numerous deadly attacks in Afghanistan, a terrorist organisation.
