An earthquake measuring 7.2 magnitude struck in Tajikistan, shaking buildings as far away as the Indian capital of New Delhi and in Pakistan, the US Geological Survey and witnesses said.
The epicentre of the quake was 111km southwest of Karakul, a sparsely populated mountainous area, at a depth of 28km, the US Geological Survey said.
A spokesman for Tajikistan's Emergencies Committee said it had no information so far on any casualties or damage from the quake.
The quake did not affect Russian military bases in Tajikistan, RIA news agency reported, citing Russia's defence ministry.
A resident of Dushanbe, the capital of Tajikistan, told Reuters news agency by telephone that the quake had been felt in the capital, but described it as moderate.
