A 7.3-magnitude earthquake has shaken the northern border region between Iran and Iraq, killing at least 348 people and injuring thousands more. One Iranian aid agency said 70,000 people needed shelter after the quake, one of the largest this year. The majority of those who died were in Iran's western Kermanshah province. Nearly 5,660 were said to be injured. Seven people died in Iraq, where people fled into the streets in the capital, Baghdad.
