The comprehensive talks between Iran and the representatives of the five permanent members of the UN Security Council plus Germany have been resumed in Turkey.
The Iranian delegation, headed by Secretary of Iran's Supreme National Security Council Saeed Jalili, arrived at Istanbul's Ciragan Palace on Friday.
The negotiations between the two sides started at the Turkish landmark, a Press TV correspondent reported.
The previous round of talks were held in the Swiss city of Geneva on December 6-7, during which both sides agreed to hold the next round of negotiations in Istanbul in late January.
