DOHA/KABUL - The United States and Taliban officials are scheduled to resume talks on Tuesday in Qatar aimed at ending Afghanistan's 18-year war, hours after a delegation of powerful Afghans and the militant group ended the Intra Afghan Dialogue, a meeting with both sides calling for an end to civilian casualties.

The US and the Taliban are getting closer to a deal that is expected to be based on a US promise to withdraw troops in exchange for a Taliban promise not to let Afghanistan be used as a base for terrorism, officials said.

While such an agreement might let the US extricate itself from its longest war, it might not bring peace between the US-backed government based in Kabul and the militants.

The Taliban have refused to negotiate with the elected Afghan government, denouncing it as a "US puppet", but in an effort to foster Afghan reconciliation, a 60-strong delegation of citizens met the Taliban for two days of talks in Qatar from Sunday.

The two sides said in a joint statement late on Monday that they were both "committed to respect and protect the dignity of people, their life and property and to minimize the civilian casualties to zero".

The Taliban, believing they have the upper hand in the war, have kept up attacks even while talking to the US and agreeing to the Afghan dialogue.

On Sunday, Taliban fighters detonated a car bomb outside a government security compound in the town of Ghazni in central Afghanistan, killing 14 and wounding more than 100, including 30 students. The deadly bombing evoked widespread condemnation.

The two sides also promised to guarantee the security of public institutions such as schools, hospitals and markets.

The deadliest year

According to the United Nations, 3,804 civilians - including more than 900 children - were killed and 7,000 wounded in 2018, the deadliest year for civilians in the conflict.

The Taliban control and influence more territory than at any point since they were ousted in 2001.

Last week, the chief US negotiator, Zalmay Khalilzad, said the latest round of US-Taliban talks, which began on June 29, was the "most productive session" since the process started last year.

"The ongoing seventh round of talks will continue until both sides put a clear agreement in place," said a senior Western official who is privy to the negotiations.

"The stage is now being set for a political settlement between the US and the Taliban. ... We can expect the US to make an announcement about troop withdrawal very soon," he said in Kabul.

This month, US President Donald Trump said he wants to pull US troops out of Afghanistan but was concerned that without a US military presence, it could be used as a base for terrorist attacks on the US.

US Secretary of State Mike Pompeo said recently the Washington wanted a deal with the Taliban by Sept 1 - ahead of an Afghan presidential election due at the end of the month.
