A large earthquake — the USGS puts it at a 7.8 on the Richter scale — has hit Iran 50 miles east of the city of Khash and near the Pakistani border.
Iranian state television reported that at least 40 people have been killed. Pakistani officials say at least five people have died.
Iran's Fars news agency reports that it's the biggest quake since a 7.7 in 1990. Fars notes that many houses in the area "are made of mud brick, which can easily crumble in a quake."
