An earthquake hit north-eastern Iran on Thursday but there were no immediate reports of casualties or major damage.
The 5.5 magnitude quake hit at 4:05 p.m (1235 GMT), 10 km outside the city of Neyshabur which is some 70 km away from the city of Mashhad, the official Irna news agency said.
"There have been no reports of casualties yet," Red Crescent official Ali Asghar Hassanzadeh told the semi-official Fars news agency, adding that windows of some houses in Neyshabur had been shattered.
The Ilna news agency said the quake lasted seven seconds and was the strongest felt in the region in 10 years.
Many parts of Iran are prone to earthquakes. At least seven people were killed in a 6.5-magnitude quake that jolted the southeast on December 20, the same region where a huge tremor killed some 31,000 people in the city of Bam in 2003.
