A 5.1-magnitude earthquake shook northern Iran on Friday, the US Geological Survey said, as Israel pounded the country with repeated waves of air strikes.
The quake, which Iran's Tasnim news agency said measured 5.2, struck at a depth of 10 kilometres (six miles) some 37 kilometres (23 miles) southwest of the city of Semnan, the USGS said.
