TEHRAN -- Syrian Interior Minister Muhammad Ibrahim al-Sha'ar said on Sunday that he is visiting Tehran for consultations with Iran about campaign against terrorism, IRNA reported.

Talking to reporters upon his arrival at Imam Khomeini airport, al-Sha'ar said that the two countries have excellent brotherly relations.

He said cooperation between the two countries is exemplary.

During his stay in Tehran, he is due to study the current campaign against terrorism.

He said campaign against terrorism requires firm determination of the two governments.

The Syrian interior minister is scheduled to confer with his Iranian counterpart Abdolreza Rahmani, President Hassan Rouhani, Secretary of Supreme National Security Council Ali Shamkhani, and Police Chief Hossein Ashtari on issues of mutual interests as well as regional developments.

Syria is in a serious war with terrorists groups such as Daesh and al-Nusra Front.

Iran has been giving military advice to both Syria and Iraq in their fight against terrorists whose brutalities have shocked the world.

From the very beginning when the insurgency started against the Syrian government in 2011 Iran warned the West and regional Arab countries that support for insurgents would lead the birth of al-Qaeda type terrorist activities.

In a report in early April, the UN said over 25,000 militants from more 100 nations have joined al-Qaeda and ISIL in Iraq, Syria and other countries.

Syria and Iraq were the destination for over 20,000 of the militants, where they went to join ISIL and the al-Nusra Front, the report added.
