For the first time since retaking power in Afghanistan, the Taliban’s leaders on Tuesday sketched out what their control of the country could look like, promising peace at home and urging the world to look past their history of violence and repression.

“We don’t want Afghanistan to be a battlefield anymore — from today onward, war is over,” said Zabihullah Mujahid, the Taliban’s longtime chief spokesman, in a news conference in Kabul, the capital.

Mr. Mujahid, a high-ranking leader, said the Taliban had declared a blanket amnesty, vowing no reprisals against former enemies. And the group has in some places appealed to civil servants — including women — to continue to go to work.
