Dubai - A major 7.8 magnitude earthquake struck Iran near the border with Pakistan on Tuesday and tremors were felt in India and Gulf states.
The US Geological Survey said the quake hit at 10:44 GMT at a depth of 15.2km. The epicentre was in southeast Iran in an area of mountains and desert.
It was located 201km southeast of the Iranian city of Zahedan and 250km northwest of Turbat in Pakistan, USGS said.
Tall buildings shook in India's capital New Delhi, sending people running into the streets, witnesses said. People also evacuated shaking buildings in Qatar and Dubai, residents said.
A powerful 6.3 magnitude quake struck close to Iran's only nuclear power station on 9 April, killing 37 people and injuring 850 as it destroyed homes and devastated two villages.
Most of Iran's nuclear-related facilities are located in central Iran or its west, including the Bushehr nuclear power plant on the Gulf coast. A US Institute for Science and International Security map did not show any nuclear-linked facilities in southeastern Iran close to Pakistan.
