The Afghan Taliban have rejected calls to extend a three-day ceasefire declared for the Muslim Eid festival.
A spokesman said the truce would end on Sunday night and operations against the security forces would resume.
Government officials urged the militants not to return to fighting, as dozens of unarmed Taliban exchanged Eid greetings with soldiers and civilians.
Meanwhile, at least 18 people were killed in a suicide attack in the city of Jalalabad, officials said.
The blast happened outside the office of the governor of Nangarhar province while officials were meeting Taliban insurgents as part of the ceasefire. Dozens were injured.
On Saturday a suicide attack in the same province, also on a gathering of Taliban and local officials, left 36 people dead. The Islamic State group said it carried out that attack.
What have the Taliban said?
The militants said there would be no extension to the ceasefire and fighters would be expected to leave government-controlled areas before sunset.
