A strong 7.5-magnitude earthquake has hit near Nepal's capital of Kathmandu and the U.S. Geological Survey says it expects heavy damage.

Early reports from Kathmandu say some houses have been damaged and walls toppled.

There is no immediate word on casualties.

The quake hit around noon Saturday and was also felt in neighboring India as well as in Pakistan.

Mohammad Shahab, a resident from Lahore, Pakistan, says he was sitting in his office when the earthquake rocked the city.

He says the tremors continued for a while but now the situation is normal in the city.

The sustained quake also was felt in India's capital of New Delhi.
