Next round of Afghan peace talks to take place in Doha - official
Peace talks began on 12 September at a luxury hotel in Doha, but negotiations are currently on a break until 5 January.
Malalai Maiwand was killed in the eastern city of Jalalabad, said Enekaas TV, the private television channel she worked for.
The attack occurred on the outskirts of Ghazni city, capital of the eastern province of Ghazni, which has seen regular fighting between the Taliban and government forces.
The attack came hours before US Secretary of State Mike Pompeo was to meet with negotiators from the Taliban and Afghan government in Qatar, amid signs of progress in talks between the two warring groups.
The military's own inspector general produced the harrowing 465-page official inquiry into events between 2005 and 2016 that detailed dozens of killings "outside the heat of battle".
Holding banners stating: "Stop Killing Us", the small gathering came as Afghanistan observed a national day of mourning and the first funerals were expected.
Many people were trampled when they tried to exit the stadium in the city of Jalalabad, the capital of Nangarhar province, leaving 10 others injured, provincial hospital spokesman Zaher Adel said.
Khalilzad said that he and General Austin Miller, the commander of US forces in Afghanistan, met several times with the Taliban to discuss "strictly adhering" to the terms of the agreement.
Negotiations will be arduous and messy, delegates warned during the opening ceremony, and are starting even as deadly violence continues to grip Afghanistan.
The talks are being held in a hotel conference room in Doha, where chairs were dotted at socially distanced intervals facing a banner emblazoned with the words 'Afghan Peace Negotiations' in four languages.
In a video posted on Facebook soon after the explosion, Amrullah Saleh, with bandages on his left hand, said he had been travelling to his office when his convoy was attacked.
The attack began on Sunday evening with a car bomb detonated at the entrance to the prison, and there were numerous other blasts heard as the IS gunmen opened fire on security guards.
Qamar Gul, 15, killed the militants when they stormed her home last week in a remote village in the central province of Ghor.
The New York Times report, which has been confirmed by several American and British media outlets, said that US intelligence concluded that a Russian military intelligence unit offered rewards to Taliban-linked militants to kill troops of the US-led coalition in Afghanistan.
Since the call by Antonio Guterres in March for ceasefires, announcements backing the end of fighting have been made in countries including Afghanistan, the Philippines and Cameroon, but conflicts have continued to rage in Libya, Yemen and elsewhere.
The pause in fighting, which came into effect on Sunday to mark the Muslim holiday of Eid al-Fitr was, for the most part, holding across the country, officials said.
President Ashraf Ghani also said the government was ready to hold peace talks with the Taliban after accepting their offer of a three-day truce over the Eid al-Fitr holiday starting Sunday that marks the end of the Muslim holy fasting month of Ramadan.
“In my more than 20-year career I have not witnessed such a horrific, brutal act.”
The Taliban has not carried out any large attacks in the city since they signed a landmark withdrawal deal with the US in February, meant to pave the way for peace in the country.
