"Mr Davutoglu will have talks with various Lebanese political and governmental circles," the source told AFP on condition of anonymity.Davutoglu will be accompanied on the visit by Qatar's Prime Minister Sheikh Hamad bin Jassem Bin Jabor Al-Thani, the source said.Both participated in a meeting on the Lebanon crisis in Damascus on Monday, where the leaders of Syria, Turkey and Qatar agreed to back mediation efforts by Damascus and Riyadh, the SANA news agency reported.Lebanon's coalition government collapsed last Wednesday when the Shiite movement Hezbollah and its allies withdrew in anticipation of being indicted for the 2005 assassination of ex-Lebanon premier Rafiq Hariri.The prosecutor of the Special Tribunal for Lebanon submitted a confidential indictment Monday against suspects in the assassination.A judge will now review the indictment, before deciding whether to confirm the charges.Lebanon was also expected to be on the agenda of talks in Ankara late Monday between Davutoglu and his Iranian counterpart Ali Akbar Salehi, according to the diplomatic source.
