That bombing was claimed by the Taliban.The blast wounded another 165 people, provincial governor spokesman Ataullah Khogyani said.Violence across the country has intensified in recent weeks as the Taliban make gains on the battlefield and IS launches deadly urban attacks.The bombing on Tuesday in the eastern province of Nangarhar was the latest in a wave of deadly insurgent attacks.It comes as Afghanistan enters a typically violent period of the year -- the holy month of Muharram, which began on Tuesday.The country’s stretched security forces will be tasked with protecting thousands of polling stations around the country at a time when they are already struggling to beat back insurgents.Delivering ballot papers and monitoring the vote, which is seen as a test run for next year’s presidential election, will be challenging, officials have warned.The dead and wounded were rushed to several hospitals in the back of pickup trucks and ambulances, overwhelming doctors and nurses as they struggled to cope with the huge number of casualties.In recent days, Taliban fighters killed nearly 60 members of the security forces in a spate of attacks in the country’s north, and threatened a provincial capital for the second time in as many months.The Taliban have long insisted on direct talks with Washington and refused to negotiate with the Afghan government, which they see as illegitimate.There has been speculation the two sides will meet again this month.The Nangarhar health department confirmed the toll.There has been no claim of responsibility for the massacre, but the Islamic State group, which has carried out most of the recent suicide bombings in Afghanistan, is active in the province..“Then the explosion happened and I found myself surrounded by blood and flesh,” Khan said from his hospital bed.Scores of demonstrators had blocked the highway between the provincial capital of Jalalabad and a major Pakistan border crossing in protest over the appointment of a local police chief when the suicide bomber blew himself up.There are already concerns about widespread fraud.It was the deadliest attack since an ambulance packed with explosives detonated in a crowded street in the heart of Kabul in January, killing more than 100 people, mostly civilians.
