JALALABAD, Afghanistan: A suicide attacker blew himself up near an Afghan security forces vehicle on Tuesday, killing at least 12 people, mostly civilians, officials said, in the latest deadly violence to rock the country.

The explosion in the eastern city of Jalalabad also left at least five people wounded and set a nearby petrol station alight, the provincial governor鈥檚 spokesman Attaullah Khogyani said.

Some of the victims were brought to hospital with severe burns, health director Najibullah Kamawal said, confirming the casualty toll.

鈥淚 saw a big ball of fire that threw people away. The people were burning,鈥� Esmatullah, who witnessed the incident, said.

Tolo News posted a video online purportedly showing several burned-out vehicles and gutted shops at the scene of the attack.

The Daesh group claimed the attack via its Amaq propaganda agency 鈥� the latest carried out by the extremists in restive Nangarhar province, which borders Pakistan.

Daesh has claimed a series of high-casualty suicide bomb attacks in the province in recent weeks, as US and Afghan forces continue offensive operations against the group.

While the Taliban is Afghanistan鈥檚 largest militant group, Daesh has a relatively small but potent presence mainly in the east and north of the country.

Tuesday鈥檚 attack comes a day after US Secretary of State Mike Pompeo expressed 鈥渉ope鈥� for peace talks between the Afghan government and Taliban, during an unannounced visit to Kabul.

Pompeo鈥檚 first trip to Afghanistan since he was sworn in as America鈥檚 top diplomat in April came amid renewed optimism for peace in the war-weary country, following last month鈥檚 unprecedented cease-fire by the Taliban and Kabul during Eid.

The Islamic holiday was marked by spontaneous street celebrations involving Afghan security forces and Taliban militants, raising hopes peace was possible after 17 years of war.

鈥淎n element of the progress is the capacity that we now have to believe that there is now hope,鈥� Pompeo told a joint press conference with Afghan President Ashraf Ghani.

鈥淢any of the Taliban now see that they can鈥檛 win on the ground militarily. That鈥檚 very deeply connected to President Trump鈥檚 strategy,鈥� he said, referring to Trump鈥檚 much-vaunted South Asia policy announced last August.

The ceasefire did not extend to the Daesh franchise in Afghanistan, which first emerged in the country in 2014 and established a stronghold in Nangarhar before spreading north.

The most recent major attack in Jalalabad on July 1 saw 19 people killed and 21 wounded when a suicide bomber blew himself up in a crowd of Afghan Sikhs and Hindus.

The group had been waiting to meet Ghani, who was visiting the city, when the bomber struck.

That came after two separate suicide attacks in Nangarhar during the cease-fire that were also claimed by Daesh.

Violence is expected to continue ahead of Afghanistan鈥檚 long-delayed legislative elections on October 20 that militants have vowed to disrupt.

Afghan security forces, already struggling to beat back the Taliban and Daesh on the battlefield, will be responsible for protecting polling stations, many of which will be located in schools.
