WASHINGTON, Oct 22 (Reuters) - A 6.2-magnitude earthquake struck Afghanistan on Thursday, the U.S. Geological Survey said, but there were no immediate reports of damage.

The quake's epicenter was 48 miles (77 km) south-southeast of Feyzabad, in the Hindu Kush region of northeastern Afghanistan. The quake, which struck at 1951 GMT, was 122 miles (196 km) deep.

CNN reported that tremors were felt in the capital, Kabul, about 165 miles (266 km) southwest of the epicenter. A quake of that magnitude can cause severe damage.

Pakistan's Geo News said the earthquake was felt in many parts of the neighbouring country, including the capital Islamabad, but there were no immediate reports of casualties. Many of the country's mountainous rural areas are however hard to reach.
