At least 13 people have died, and hundreds injured after an earthquake rocked Afghanistan and Pakistan, with tremors felt in India.

In northwest Pakistan, at least nine people were killed and 44 injured, a government official said on Wednesday. Hospitals in northern Khyber Pakhtunkhwa province were put into a state of emergency overnight.

Landslides have caused damage in the Swat district, 180km (112 miles) northwest of the capital Islamabad and more than 20 buildings have been damaged.

Four people were killed and 50 injured in Afghanistan, a health ministry official there said.

Houses and buildings in both countries were also damaged, authorities said.

The quake was felt over an area more than 1,000 kilometers (621 miles) wide by some 285 million people in Pakistan, India, Uzbekistan, Tajikistan, Kazakhstan, Kyrgyzstan, Afghanistan and Turkmenistan, the European-Mediterranean Seismological Centre said.

The epicenter was in the Hindu Kush mountains, in the sparsely populated northeastern Afghan province of Badakhshan, 40km southeast of Jurm village, at a considerable depth of 187km, the U.S. Geological Survey said.

Strong tremors shake north India and NCS maps the quake at 6.6 magnitudes. The earthquake, with its epicenter at 133km south by southeast of Fayzabad in northern Afghanistan, was mapped at 10.17.27 p.m. (IST) by India’s National Centre for Seismology.
