Earthquake rocks south Asia

ISLAMABAD, Pakistan (CNN) -- An earthquake measuring magnitude 6 shook parts of Afghanistan, Pakistan and India on Thursday, seismologists reported.

The quake was centered in the Hindu Kush mountain range in Afghanistan, about 110 kilometers (70 miles) west of Chitral, Pakistan, the U.S. Geological Survey said. It was felt first in the Afghan cities of Kabul and Jalalabad around 11:35 a.m. (2:05 a.m. EST).

In Kabul, CNN's John Raedler was in the fifth floor of the Intercontinental Hotel when the quake struck. The shuddering appeared to last about 10 seconds, shaking the floor and walls, he said. Two clocks hanging on the wall began swinging.

Looking over Kabul from the hotel, he said, there were no obvious signs of earthquake damage.

Two minutes later, the quake was felt in Islamabad, Pakistan. It lasted at least one minute, CNN staff there said.

Parts of northern India, including sections of New Delhi, were also shaken by the earthquake.
