Qatar's foreign ministry announced "the success" of intra-Afghan peace talks in a tweet on Tuesday as Taliban and rival parties are reported to have pledged to reduce violence in Afghanistan at a meeting in Doha.

"The appeal and promise to reduce violence in Afghanistan" was the most significant part of a joint statement issued at the gathering, said Germany's Afghanistan envoy Markus Potzel after the talks concluded on Monday. 

Wary representatives of Afghan society met Taliban officials in Qatar for the peace talks, with bloody insurgent attacks back home casting a pall over efforts to end Afghanistan's years of war. 

The Taliban on Sunday detonated a car bomb outside a government security compound in central Afghanistan killing 14 people and wounding 180, including scores of children. 

The attack came at the onset of the two-day meeting that was meant to open the way to a peace process that should build on a hoped-for deal between the United States and the Taliban to end the longest ever war. 

"It is very hard to sit across from those men who are waging a war against innocent Afghans, but it is also a test of our commitment to peace," said a senior Afghan official involved in the talks. 

The Taliban and U.S. officials are trying to strike a deal on a Taliban demand for the withdrawal of the U.S. and other foreign forces and a U.S. demand that the Taliban not allow Afghanistan to be used as a base for terrorism. 

"We think the gap between the U.S. and Taliban is narrow now. We hope both sides will reach an agreement this month about the outstanding issues," said Qatar's lead mediator Mutlaq Bin Majid Al-Qahtani. 

U.S.-Taliban talks, the seventh since last year, was held on Tuesday in Doha, while U.S. officials looked to clinch a deal by September ahead of an expected Afghan presidential election. 

But the Taliban have refused to negotiate with the U.S.-backed Afghan government, denouncing it as an American puppet. 

So while the 60-member delegation of Afghan representatives in Qatar included officials, they were not present in their government capacity. 

"I am here as an Afghan, but I am not sure if the Taliban view themselves as Afghans before anything else," said the senior official, who spoke by telephone from Qatar but declined to be identified. 

During their 1996-2001 rule, the Taliban barred women from working outside their homes and said women could only go out in public if accompanied by a male relative. 

Afghan society has taken huge strides since the Taliban were ousted weeks after the September 11, 2001, al Qaeda attacks on the U.S., and many Afghans are nervous about preserving the progress under some sort of a power-sharing government that might be part of a deal to end the war. 

The talks, facilitated by Germany and Qatar, have touched on how Afghanistan might be organized.  

"The Taliban prefer Islamic Emirates style of government while we ask for a republic," said Khalid Noor, the son of a powerful politician from northern Afghanistan, Atta Mohammad Noor.  

Some Afghan officials fear the United States and the Taliban will strike a deal enabling the U.S. to get out of a war that President Donald Trump is impatient to end, leaving government forces to battle on alone. 

Such fears are compounded by ongoing relentless violence. 

The Taliban now control and influence more territory than at any point since 2001. 

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