Twelve were killed and 100 others were wounded in a car bomb explosion in front of a police headquarters in western Afghanistan, and no one claimed responsibility, while 4 security personnel were killed in a separate attack by the Taliban, which accused Washington of violating the peace agreement.

The Afghan Interior Ministry spokesman said that the first attack - which resulted in killing and wounding dozens - took place in Ghor Province, west of the country.

The spokesman held the Taliban responsible for the incident, which no party has yet claimed responsibility for.

A health official in Ghor, Jumah Gul Yaqoubi, told AFP that among the victims were security personnel.

In turn, the spokesman for the governor of Ghor Arif Abeer confirmed that "the explosion was very strong. There are dead and wounded people, and people are taking them to hospitals." He indicated that the explosion damaged nearby buildings that deal with women and people with special needs.

In a separate attack, Al-Jazeera correspondent reported that 4 Afghan forces were killed and 3 wounded in an attack by Taliban militants on checkpoints on the outskirts of the city of Faizabad, the capital of Badakhshan Province in the north of the country.

Taliban accuse Washington

Meanwhile, the Taliban accused US forces of violating the Doha Agreement by carrying out massive air strikes in Helmand Province, southern Afghanistan.

Taliban spokesman Muhammad Yusuf Ahmadi said that drones and other fighter jets carried out attacks in recent days in different areas of Helmand, as well as air strikes in Farah and other provinces.

Ahmadi said that all these strikes are a direct and clear violation of the Doha Agreement, noting that the consequences of continuing these acts fall on the US side.

For their part, US forces in Afghanistan rejected the Taliban’s claim that the US had violated the Doha Agreement.

"The American air strikes in Helmand and Farah were only to defend the Afghan forces, as they are being attacked by the Taliban and come within the framework of the Doha Agreement and the joint declaration between the Afghan government and the United States," a spokesman for the US forces in Afghanistan, Colonel Sunny Legg, wrote on his Twitter account.

"The whole world has witnessed Taliban offensive operations in Helmand Province, which resulted in the injury and displacement of thousands of innocent Afghan civilians. We reiterate our call to all parties to reduce violence," he added.

Peace talks between the Taliban and the Afghan government began in Doha last month, but the violence did not stop on the ground.

In the context of peace developments, the President of the Supreme Council for National Reconciliation in Afghanistan Abdullah Abdullah met in Tehran with Iranian Foreign Minister Muhammad Javad Zarif.

Iranian Foreign Ministry spokesman Saeed Khatibzadeh stated that his country will do everything it can to support the Afghan national dialogue, and that it supports the stability of Afghanistan.

Abdullah Abdullah, heading a high-ranking delegation, is visiting Tehran for a three-day visit, during which he will meet with a number of Iranian officials, to discuss bilateral relations and developments in the Afghan dialogue.

The Afghan official had visited Pakistan and India prior to his arrival in Tehran, and some Iranian websites reported that he was trying to achieve regional consensus, which would contribute to achieving stability in Afghanistan and the success of the peace talks between the Taliban and the United States in Doha.
