A powerful 7.8 magnitude earthquake has shaken south-eastern Iran, close to the border with Pakistan, causing high-rise buildings to sway as far away as India and the Gulf states.
Pakistani officials say at least 35 people were killed on their side of the border and hundreds of houses have been destroyed.
The US Geological Survey says the quake was as powerful as the one that hit Haiti in 2010.
National media report 27 people were injured while Iranian state TV has denied earlier reports that 40 people died.
Last week a 6.3 quake struck southern Iran, killing more than 30.
