Iran is set to meet with officials from Britain, France, and Germany -- the so-called European three (E3) -- on July 25 in Istanbul to discuss the country’s nuclear program as Western nations turn up the pressure on Tehran to reach a settlement or face new sanctions.

Iran, Britain, France and Germany will hold nuclear talks in Istanbul on Friday, an Iranian Foreign Ministry spokesperson said early on Monday, following warnings by the three European countries that failure to resume negotiations would lead to international sanctions being reimposed on Iran.
