The US signed a landmark deal with the insurgents last year, agreeing to withdraw all of its troops from the country in return for security guarantees after a stalemate on the battlefield.

"The other side have violated the agreement, almost every day they are violating it," Mohammad Naeem, a Taliban spokesman in Qatar, told AFP.

"They are bombarding civilians, houses and villages, and we have informed them from time to time, these are not just violations of the agreement but violations of human rights."

The US military has in recent months carried out air strikes against the Taliban fighters in defence of Afghan forces in some provinces.

Pentagon spokesman John Kirby told reporters on Thursday that the Biden administration remains committed to the Taliban-US deal and ending the war "in a responsible way".

However, he said, "the Taliban are not meeting their commitments to reduce violence, and to renounce their ties to Al-Qaeda".

"We are still involved in trying to get a negotiated settlement," he added.

The agreement, signed in Doha last year, required the Taliban to halt attacks on US forces, sharply decrease the level of violence in the country, and advance peace talks with the government in Kabul.

In return, the United States would steadily reduce its force level in the country, and remove all forces by May 2021.
