Syria's prime minister has arrived in Tehran for talks with Iranian leaders ahead of a peace conference in Geneva aimed at ending his country's civil war.
During his three-day visit, Wael al-Halqi will meet President Hassan Rohani, Foreign Minister Mohammad Javad Zarif, and National Supreme Security Council chief Ali Shamkhani.
After his arrival, Halqi said he would discuss the Syrian crisis as well as bilateral issues, such as cooperation in the fields of energy, electricity, oil exports, infrastructure, and health.
The visit comes a day after Syria said its delegates would attend the so-called Geneva 2 conference, scheduled for January 22.
Iran is Syrian President Bashar al-Assad's main regional backer.
It is not yet clear whether Iran -- which is accused by Syrian rebels of arming Assad's forces -- will participate in Geneva 2.
