Iranian Foreign Minister Manouchehr Mottaki said that Iran has agreed to hold talks with the five UN Security Council permanent members and Germany (G5+1) in Turkey.
- Iran is invited to attend the next round of talks over Syria's future, along with the representatives from the United States, Russia, Saudi Arabia, Turkey, Britain, France, Germany, Jordan, the United Arab Emirates, and the United Nations mediator for Syria, Staffan de Mistura. The next round of the "Vienna II" meeting is expected to start tomorrow and continue Friday in Vienna, Austria.
- Talks between Iran and the five permanent members of the UN Security Council plus Germany break down without an agreement to end the eight-year-old impasse over Iran's nuclear program, after Iranian officials refused to negotiate unless preconditions including an immediate halt to UN sanctions on Iran were met.
- Turkey summons the ambassador of Germany after at least 10,000 people rally in Cologne in support of the referendum.
- A memorandum is signed by Russia, Iran, and Turkey calling for de-escalation of the Syrian Civil War, although neither the Syrian government nor the Syrian opposition are signatories.
- The first synchrotron in the Middle East, SESAME, opens in Jordan, marking a rare cooperation between Iran, Israel, Turkey, and the Palestinian Authority.
