A 7.3-magnitude earthquake has shaken the northern border region between Iran and Iraq, killing at least 214 people and injuring more than 2,800.

One Iranian aid agency said 70,000 people needed shelter after the quake, one of the largest this year.

Most of those who died were in Iran's western Kermanshah province, officials told state media.

At least seven more died in Iraq, where people fled into the streets in the capital, Baghdad.
