Ghani had been due to address the rally in Charikar, capital of Parwan province, north of Kabul, when the suspected militant attack occurred.
The Taliban have also claimed responsibility for a separate bomb explosion near the US Embassy in Kabul. Khalilzad sought a comprehensive peace deal including a cease-fire, US troop withdrawal and a Taliban pledge to hold talks with the Afghan government, as well as a Taliban counterterrorism pledge against al Qaeda and the Islamic State-Khorasan.
Presidential elections are scheduled for September 28, and the Taliban has condemned the vote, threatening related activities and warning Afghans to stay away.
What he read in the draft outlining the now collapsed deal left Ghani and his officials - who were shut out of the talks by the Taliban refusal to negotiate with what they considered an illegitimate "puppet" regime - badly shaken and resentful, said a senior Kabul official close to the Afghan leader.
"And for days, Afghanistan has endured blackouts and other challenges as a result of Taliban attacks against power transmission lines which carried electricity to hospitals, schools, and homes in many areas of the country, Pompeo said on Tuesday".
Khalilzad and some of Ghani's rivals, however had talked of establishing an interim administration to run the country while a peace deal was implemented.

US President Donald Trump withdrew from the Afghan peace deal, calling the deal "dead" last week after months of negotiations to end the 18-year war in Afghanistan.
At least 26 people, including four members of Afghanistan's security forces, were killed and 42 others wounded, according to the Interior Ministry.
"We already warned people not to attend election rallies, if they suffer any losses that is their own responsibility", the statement said.
There were many women and children among the casualties in the bombing near Ghani's rally, said Dr Qasim Sangin, a local official. The two sides had been seeking to reach an accord on the withdrawal of thousands of American troops from Afghanistan in exchange for Taliban security guarantees. The Taliban killed another American troop on Monday, marking the first USA fatality since Trump deemed the peace talks "dead" and the 17th this year alone.
Although the Afghan president witnessed the explosion first hand, Hamed Aziz, his campaign spokesman, reportedly indicated that he is "safe and unharmed".
Taliban chief negotiator Sher Mohammad Abbas Stanikzai told the BBC that negotiation remained "the only way for peace in Afghanistan".
