At least 20 dead in Afghanistan suicide attack during ceasefire

A suicide bomber blew himself up in a crowd of Afghan Taliban, security forces, and civilians celebrating an unprecedented ceasefire in the war-torn country today, killing at least 20 people, officials said.

The attack came as President Ashraf Ghani announced an extension of the government's week-long ceasefire with the militant group after both sides agreed to halt hostilities for Eid.

There was no immediate claim of responsibility for the blast that also wounded at least 16 others marking the suspension of fighting in Rodat district of Nangarhar province, but an Afghan security source told AFP that the Islamic State group was to blame.

"A suicide bomber detonated among people, security forces and Taliban who were celebrating the ceasefire," provincial governor spokesman Attaullah Khogyani told AFP.

He said at least 20 people had been killed and 16 others wounded. Provincial health director Najibullah Kamawal confirmed the death toll but said 25 wounded had been taken to hospital.

Ghani made his announcement in a rare televised address to the nation, in which he also asked the Taliban to extend their three-day ceasefire which is due to end tomorrow.

"I order the security forces to remain on their defensive positions," Ghani said, adding details of the extension would be released later.

The government's ceasefire, which was due to end on Tuesday, did not include the IS.

On the first two days of Eid, Taliban fighters, Afghan security forces and civilians hugged and took selfies with each other across the country, in an outpouring of emotion over the ceasefire.

In the contested district of Bati Kot in Nangarhar, Taliban fighters carrying assault weapons and rocket-propelled grenade launchers travelled by car and motorbike, waving Afghan and Taliban flags.

Afghan forces manning checkpoints offered Eid greetings to the fighters, embracing and posing for photos with the same people they are usually trying to kill -- a scene that would have been unthinkable only a few days ago.

Villagers also flocked around the insurgents, hugging them and happily taking selfies with the heavily armed fighters as they celebrated the Muslim holiday capping the holy month of Ramadan.

"I am here to offer greetings to our brothers in the police and army," Taliban commander Baba told AFP.

"We have held the ceasefire well so far. Everyone is tired of war and if our leaders order us to continue the ceasefire, we will hold it forever."
