At least 50 Afghan civilians have been killed in separate incidents, as the West-backed Kabul government and Taliban fighters have stepped up attacks since a peace deal between the armed group and the US collapsed earlier this month.

A US-backed air raid conducted by the Afghan security forces accidentally hit a farmland in Nangarhar province killing about 30 civilians and injuring 40 others, while at least 20 people were killed in Zabul province in a suicide car bomb claimed by the Taliban group.

Afghan officials said the drone attack on Wednesday night was aimed at destroying a hideout used by Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group fighters, but it accidentally targeted farmers near a field in Wazir Tangi area of Khogyani district in Nangarhar province.

Sohrab Qaderi, a provincial council member in Nangarhar said a drone strike killed 30 workers in a pine nut field and at least 40 others were injured.

The defence ministry in Kabul confirmed the strike, but refused to share casualty details immediately.

Attaullah Khogyani, a spokesman for the provincial governor of Nangarhar confirmed the air strike.

“The government is investigating the incident, so far nine bodies were collected from the attack site near a pine nut field,” he said.

US forces were not immediately available for a comment.

Malik Rahat Gul, a tribal elder in Wazir Tangi said the air raid happened at a time when tired workers, mainly daily wage earners, had gathered near their tent after harvesting pine nuts in a field nearby.

“The workers had lit a bonfire and were sitting together when a drone targeted them,” said Gul.

Earlier this month, four brothers were killedin a raid by the CIA-trained and funded 02 Unit of the National Directorate of Security (NDS) spy agency.

Spike in Taliban attacks

The Taliban fighters wanted to target a training base for Afghanistan’s powerful spy agency, NDS, but parked the explosives-laden truck outside a hospital gate nearby, a defence ministry source said.

Al Jazeera’s Rob McBride, reporting from the capital, Kabul, said several women, children, health workers and patients in the hospital were critically injured in the blast.

“[The] truck bomb that drove up against an exterior wall of the NDS building detonated, but right next door was a provincial hospital that has taken the brunt of this explosion. …the death toll is likely to rise,” he said.

The spike in Taliban attacks comes as Afghanistan prepares for a presidential election scheduled to be held on September 28.

The Taliban has warned that its fighters will step up their campaign against the Afghan government and foreign forces to dissuade people from voting in the presidential election.

“The government is still going ahead with its preparation for elections and trying to open up the number of polling stations,” McBride said.

“As the Taliban say they are still open to peace talks, the Afghan government is saying it has to resume only after elections.”

More than 9 million Afghans are expected to vote in the presidential election, for which which the government has deployed more than 70,000 security forces across the country.

US President Donald Trump abruptly ended talks this month with the Taliban for a deal on the withdrawal of thousands of American troops from Afghanistan, in exchange for security guarantees from the Taliban.

The talks, which did not include the Afghan government, were intended to lead to wider peace negotiations to end the 18-year-long war in Afghanistan.
