At least one person has been reported killed in clashes between Pakistani and Afghan soldiers overnight at a border crossing on the Khyber Pass.
An Afghan official said on June 13 that six soldiers were also wounded in the incident at the Torkham Gate crossing in the mountainous region between the two countries.
The Pakistani Army said one of its soldiers was wounded in the fighting.
The incident reportedly broke out at roughly 9 p.m. local time on June 12 and continued for several hours.
Afghanistan's chief executive officer, Abdullah Abdullah, said on Twitter that "we currently have agreed on a ceasefire with #Pakistan. We hope this problem will end through the work by diplomatic addresses."
He added that "the current fight Pakistan started doesn't help anyone's interest."
"Pakistani security forces responded to Afghan firing effectively," said Ayub Hussainkhil, a Pakistani border-police commander in eastern Afghanistan. "We have received reinforcement and are ready to defend our country until the last drop of blood in our bodies."
Afghan officials have long accused Pakistan of aiding Islamic militants that seek to topple the Kabul government.
Pakistan denies the charges and its officials say they are building a border gate near Torkham, a Pakistani town close to the border, to prevent militants from crossing into Afghanistan.
Pakistan and Afghanistan share a 2,200-kilometer disputed border that is very porous.
