A strong earthquake shook northeastern Afghanistan early Monday, sending people running from their homes, but there were no immediate reports of damage, witnesses and officials said.
The 6.0-magnitude quake struck at 3:43 am (23:13 GMT Sunday), around 275 kilometres (170 miles) northeast of the Afghan capital Kabul and near the border with Pakistan, the US Geological Survey said.
The quake, which struck in the remote Hindu Kush mountain range, was registered at a depth of 190 kilometres, it said.
Shockwaves were felt as far away as Islamabad, where people ran from their homes fearing that buildings would collapse, an AFP correspondent in the Pakistani capital said.
