A series of eight earthquakes hit the Iran-Iraq border area and rattled Baghdad on Thursday, apparent aftershocks of a temblor that struck the mountainous region in November and killed over 530 people.
The first quake of 5.5 magnitude hit area at about 10:00 a.m. (0700 GMT), located some 18 km east of the Iraqi town of Mandly on the border with Iran, at depth of 10 km, according to the U.S. Geological Survey (USGS). It says the quake's depth was 10 kilometers, or 6.2 miles.
Several other earthquakes hit eastern Iran, according to USGS, and were also felt in Iraq's eastern and central provinces.

In November, a magnitude 7.3 quake struck the same border region between Iran and Iraq, killing 530 people and injuring more than 9,000. No injuries or damage were reported. The last deadly quake was in 2003, where a 6.6 magnitude natural disaster killed 26,000 people in the city of Bam.
Many buildings collapsed or sustained major damage in November's quake.
Iran is located over major fault lines and is prone to near-daily earthquakes. In 2003, a 6.6 magnitude quake had flattened the historic city of Bam, killing 26,000 people, said reports.
