Earthquake hits Iran-Iraq, More than 300 die in heavy tremor
As aftershocks continued on Monday and as rescuers sped up their operation, Iran's state news agency IRNA confirmed the death toll, saying at least 382 of the injured remain in hospital.
The US Geological Survey (USGS) said Sunday's powerful quake hit close to Halabjah, southeast of Sulaymaniyah, a city in the semi-autonomous Kurdish region of northern Iraq.
The tremor, which was felt as far away as Qatar, struck at 9:18pm local time (18:18) GMT. Its epicentre was at a depth of 33.9km.
Most of the victims are believed to be in the Iranian town of Sarpol-e Zahab.
Crossed by several major fault lines, Iran is one of the world's most seismically active countries.
In 2003, a 6.6 magnitude earthquake flattened the historic city of Bam in southeastern Iran, killing some 26,000 people.
