A powerful earthquake has struck northern Afghanistan, with tremors felt as widely as Pakistan and northern India.
The magnitude 7.5 quake was centred in the mountainous Hindu Kush region, 75km (46 miles) south of Faizabad, the US Geological Survey reported.
Buildings were evacuated in the capitals of all three countries and communications disrupted in many areas.
Initial reports say at least 13 people have been killed in Pakistan.
There are also reports of a stampede triggered by the quake at a girls' school in the Afghan province of Takhar, which left 12 students dead.
Another five people died in the eastern Afghan city of Jalalabad, hospital sources said.
Officials said the quake happened at a depth of 212km. The magnitude was initially put at 7.7 but later downgraded.
