JALALABAD: Ten Afghan fighters for the Islamic State group have surrendered their weapons in eastern Afghanistan, in a first since IS militants moved into the country, officials said Thursday.

The Islamic State in Afghanistan and Pakistan, named a year ago by the group's leadership, has stepped up its offensive in the east of the country in recent weeks.

IS fighters have even chased Taliban rebels from strongholds in Nangarhar Province next to the Afghan-Pakistan border, but they have also faced attacks from the Afghan army and NATO drone strikes.

"For the first time, ten so-called Daesh fighters including their two commanders along with ammunitions have joined the Afghan government peace process," said a spokesman for the Nangarhar provincial governor's office, using an Arabic abbreviation for the IS group.

Fourteen Taliban fighters had also "chosen the path of peace," he added.

Malik Nazir, head of the provincial peace committee, said the 10 IS men were active in the Shinwar district between the provincial capital Jalalabad and the Pakistani border.

"We will provide good security and job opportunity for the surrendered men, and will provide basic facilities so that they don't go to fight again," said Nangarhar deputy provincial governor, Mohammad Hanif Girdiwal.

One of the IS fighters, Zeitoun, told a ceremony to mark their defection that he was "happy to join the peace process. I fought against the government in Daesh ranks for the last nine months."

IS fighters in Afghanistan are often former Taliban fighters disappointed with their leadership, but also insurgents from neighbouring countries.
