DAMASCUS:- Iranian Foreign Minister Mohammad Javad Zarif has said that Idlib in northwestern Syriainfo-icon must be cleansed of terrorists and returned to the government fold as he arrived in Damascus for key talks. 

"Terrorists operating in the remaining parts of Idlib must be cleansed, and the region be returned to the people of Syria," Zarif told reporters on Monday upon arrival in the Syrian capital. 

As Syrian President Bashar al-Assad attempts to turn military success into postwar reconstructioninfo-icon, foreign-backed terrorists in Idlib remain the last major hurdle to the program. 

The Syrian armyinfo-icon gears up for a major offensive to retake the last terrorist stronghold, but it is facing threats of being hit by the USinfo-icon and its allies if a chemical attack takes place in the province.

Russiainfo-icon and Syria say staging a false flag chemical attack has been in the works for some time by militants and British "special forces" in order to give the US a pretext to hit the government.  

Russian Foreign Minister Sergei Lavrov said on Monday that the situation in Idlib Province could not be tolerated indefinitely.

Speaking in Moscowinfo-icon, the top diplomat said the Syrian government had every right to wipe out militants in Idlib, Interfax news agency reported.

Lavrov had earlier called the Idlib-based terrorists as an "abscess" which needs to be taken out before harming thousands of civilians who live there.

Russia's foreign minister says the terrorist "abscess" in Syria's Idlib must be destroyed before harming more civilians.

In a joint press conference with his Saudi Arabian counterpart Adel al-Jubeir in Riyadh, Lavrov said last Wednesday that terrorists holed up in the city were using ordinary people as human shields.

"So, from all standpoints, this abscess has to be liquidated," the Russian foreign minister said.

For months, Syria has been planning the decisive operation in Idlib, the last of its provinces that still remain under the control of militants.

Presidents of Iraninfo-icon, Russia and Turkeyinfo-icon are due to meet in Iran for a third summit on Syria on September 7. On Wednesday, Zarif made a previously unannounced visit to Ankara and held "fruitful" talks with President Recep Tayyip Erdogan.

Turkish Foreign Minister Mevlut Cavusoglu, who attended the meeting, said bilateral ties and Syria were on the agenda.

Turkey has been keeping a wary eye on the possibility of the Idlib offensive, as it seeks to bring peace to Syria along with Iran and Russia.

Zarif said on Monday, "Syria's territorial integrity must be preserved, all ethnic groups must collectively start the reconstruction process, and the displaced must return to their families."

The Iranian foreign minister was due to meet Syrian President Bashar al-Assad, Prime Minister Imad Khamis, and his counterpart Walid al-Muallem.

Iranian Defense Minister Amir Hatami was in Damascus last week and signed a "defense and technical agreement" designed to ensure the continued presence and participation of Iran in Syria's reconstruction.

Tehraninfo-icon has provided steady military advice to Syria in its seven-year fight with terrorists. On Monday, Foreign Ministry spokesman Bahram Qassemi said the support, including Iran's military advisory presence in Syria, will continue.  

"Iran will remain a supporter of the Syrian government in its efforts to remove terrorists,and continue its advisory role and help the Syrian government in the upcoming Idlib campaign," he told a weekly news briefing in Tehran. 

Qassemi said the Syrian government "has the right to fight against terrorists and purge them entirely from its territory."

"Idlib is a complicated issue as it is the last stronghold of rebels operating against the Syrian national government, and is also home to terrorist elements," he said.

"As part of its battles and victories over terrorists, the Syrian government is resolved to end the plague [of terrorism] in this province as well," he added.

The spokesman said the imminent Idlib offensive has worried "certain sponsors of terrorists" who have launched "a massive propaganda campaign" to forestall the purge. 

Qassemi also touched on the upcoming summit of President Hassan Rouhani of Iran, President Erdogan and Russian President Vladimir Putin in Tehran, saying it can definitely help return peace, stability, and security to Syria.

Nevertheless, "it is not logical to assume that a single summit would resolve a longstanding issue like that of Syria, but a political solution is still the only possible way," he added.
