News reports from Iran say a powerful earthquake has hit the southeastern region of the country.

The state-run IRNA news agency says the quake's intensity measured 5.9 on the Richter scale. It struck early Sunday in the southeastern province of Sistan-Baluchistan, which borders Pakistan.

The U.S. Earthquake Information Center says its instruments reported the quake had an intensity of 6.0.

No casualties were reported during the first hours after the earthquake.

Several major fault lines in the Earth's crust run through Iran, and much of the country is seismically active. A strong earthquake that hit southeast Iran on February 22 killed more than 600 people and destroyed several villages. That jolt measured 6.4 on the Richter scale and was centered on the town of Zarand in Kerman province, about 700 kilometers southeast of Tehran.

Another earthquake hit southeastern Turkey early Saturday, injuring at least seven people and triggering an avalanche in rural Bingol province.
