At least nine people were killed and 44 injured in northwest Pakistan by a magnitude 6.5 earthquake that struck in neighboring Afghanistan late on Tuesday, a Pakistani government official said.
At least two people were killed in Afghanistan, a disaster agency official there said.
The quake was felt over an area more than 1,000 km wide by some 285 million people in Pakistan, India, Uzbekistan, Tajikistan, Kazakhstan, Kyrgyzstan, Afghanistan and Turkmenistan, the European-Mediterranean Seismological Centre said.
