It was just after midnight on the morning of September 11 in Kabul when the sound of an explosion echoed across the capital.
President Donald Trump recently canceled scheduled talks between the USA and the Taliban, the Islamic insurgent group ousted from power during the invasion, which still maintains strongholds in the country.
There were no injuries reported. He added, per the Washington Post, "I'm not even talking about nuclear power".
"They're dead. They're dead", Mr. Trump wrote.
For almost a year, US envoy Zalmay Khalilzad has been negotiating with the Taliban on issues including a USA troop withdrawal and Taliban guarantees to keep Afghanistan from again becoming a launch pad for global terror attacks.
The Afghan Taliban, however, say they had agreed to a "partial ceasefire" limited to the foreign forces in Afghanistan as part of the proposed peace agreement with the United States but that the terms of the deal would have come into effect only after it had been signed. "The last time hearing those precious words, 'I love you, '" said Trump, who began the day observing a moment of silence on the South Lawn with first lady Melania Trump and White House staff.
About 14,000 USA soldiers remain in the country and Trump has called their ongoing deployment "ridiculous", including the many billions of dollars spent in the war.
Trump said he called off plans for secret peace talks with the Taliban at Camp David, Maryland last Sunday when he learned that a Taliban-claimed suicide attack had killed 12 in Kabul, including a US service member. As part of the proposed deal, the United States would withdraw 5,400 troops from Afghanistan within 20 weeks. Trump has called it "ridiculous" that they are still in Afghanistan after so many years and so many billions of dollars have been spent.
Recent informal talks between the Taliban and representatives of Afghan society in Doha and Moscow addressed some key issues for peace, Yamamoto said. "I want to see if we can get to the final outcome we needed'".
"We do not seek conflict, but if anyone dares to strike our land, we will respond with the full measure of American power and the iron will of the American spirit, and that spirit is unbreakable", he said.
About 30 Taliban militants were killed in an airstrike in Afghanistan's Takhar province, a local source said on Wednesday.
