Original story:

A major earthquake hit Afghanistan, Pakistan and India at 5:13 a.m. EDT Monday with tremors being felt as far as the Indian capital of New Delhi, local news reports said. Dawn, a Pakistani newspaper, reported at least 12 deaths in the affected parts of the country. 

The epicenter of the magnitude-7.5 earthquake was reported to be in northern Afghanistan's Hindu Kush region, by the U.S. Geological Survey. The USGS, which had originally reported it to be a 7.7-magnitude quake, estimated the epicenter to be 45 kilometers (28 miles) south-southwest of Jarm, Afghanistan, about 265 kilometers northeast of the capital Kabul. The agency also reported that the quake occurred at a depth of about 132 miles.

According to various reports, the powerful quake was felt as far southeast as Pakistan's capital of Islamabad and India's capital of New Delhi. 

Pakistani local media reported a landslide in the Gilgit area, and at least four deaths in the country's northern regions. Dozens have been reportedly injured. Reports also said people left their homes in Peshawar, Abbottabad and the capital Islamabad. There were also early reports of a school building collapse in the northeastern region of Sargodha. Pakistani authorities have also warned of more aftershocks in the next 24 hours. 

Local reports said people in New Delhi were seen evacuating office buildings while the Times of India reported that the Delhi metro has also halted services. Initial reports said the quake also affected India’s northern border state of Jammu and Kashmir. Phone lines in the state capital, Srinagar, were cut off following the quake. No casualties have been reported so far.

In a tweet, Indian Prime Minister Narendra Modi called for an assessment of the situation and offered help to the governments of Afghanistan and Pakistan.
