KABUL: War-weary Afghanistan was hit with its third straight day of bloody carnage on Thursday, as a Taliban car bomb flattened a hospital and killed 20 people in the south, while at least nine others died in a drone strike in the east.

The surge in violence, with civilians paying the heaviest price, has come after US President Donald Trump called off talks with the Taliban that could have seen Washington begin withdrawing troops, and as the country gears up for a presidential election.

The insurgents responded to Trump`s declaration that the talks were `dead` earlier this month by promising to continue fighting, and have vowed to target the Sept 28 polls, Afghanistan`s fourth presidential election since the Islamist group was ousted f rom power in 2001.

Thursday`s bloodshed began near dawn, when the Taliban killed at least 20 people and wounded 90 after a car bomb destroyed a hospital in the southern Afghan city of Qalat.

Hours later, reports emerged of an overnight drone strike in eastern Nangarhar province said to have killed at least nine civilians who had been camping in the mountainous region as they collected pine nuts.

The US is the only member of theinternational coalition in Afghanistan that provides air support in the conflict, but there was no immediate statement from its forces in Afghanistan, the United Nations or Nato.

The strike came just hours after fourpeoplewerekilledonWednesday when unknown gunmen and a suicide bomber stormed a government building in nearby Jalalabad, capital of Nangarhar province.

On Tuesday, the Taliban killed nearly 50 people in two separate attacks one on a campaign rally for President Ashraf Ghani in the central province of Parwan, and the other in Kabul.

Ordinary Afghans continue to bear the brunt of the nearly 18-year conflict, with more civilians killed in the Afghan war in 2018 than during any other year on record, according to the UN.

Zabul Governor Rahmatullah Yarmal said Thursday morning`s car bomb had targeted a National Directorate of Security building in Qalat and destroyed an adjacent hospital, with two local officials confirming the death toll.

Residents near the blast, which was claimed by the Taliban, said the explosion rattled homes and shattered windows and was followed by gunfire.`It was horrific,` said university student Atif Baloch, who saw women and children being dragged from the scene by rescuers.

Panic also spread among residents searching for f amily at the hospital.

Drone strike In Nangarhar, District Governor Shamsul Haq said that at least nine people were killed and six wounded in the drone strike in Khogyani district, adding that all those killed were civilians.

Other officials gave varying tolls, with one of them putting the deaths at 30.

`The strike was supposed to target Daesh (the militant Islamic State group) fighters, but it mistakenly hit the civilians,` said Nangarhar police spokesman Mubarez Atal.

One survivor, 22-year-old Pir Mohammad, said that labourers had come from other provinces to pick pine nuts and were asleep in their tents when the strike began.

`Many of our friends were killed for no reason, and dozens of others were wounded,` he said from a hospital in Jalalabad, where he was being treated for shrapnel wounds.

Fawad Aman, a deputy defence ministry spokesman, said the ministry was investigating the reports.-AFP
