Iran's foreign minister Abbas Araqchi will visit Damascus on Sunday, before visiting Türkiye as part of a regional tour, foreign ministry spokesperson Esmaeil Baghaei told state media on Saturday.
Earlier, Araqchi and his Russian counterpart voiced support for Syria on during a major attack by opposition groups, Iranian state media reported.
Araqchi told Russia's Sergei Lavrov in a phone call that the attacks were part of an Israeli-US plan to destabilize the region, state media said.
According to a statement from the Russian Foreign Ministry about the call, both sides "expressed extreme concern about the dangerous escalation of the situation in Syria due to the terrorist offensive by armed groups in the Aleppo and Idlib provinces".
The ministers agreed on the need to intensify joint efforts aimed at stabilizing the situation in Syria.
Iran's foreign ministry also condemned what it called "aggression by terrorist elements" against its consulate in Syria's city of Aleppo during the current opposition advances, Iranian state media reported.
"The consul-general and all members of the consulate of Iran in Aleppo are in good health," spokesperson Baghaei told state media.
Earlier on Saturday, Russia's Lavrov spoke on the matter with his Turkish counterpart, Hakan Fidan.
For his part, Fidan spoke by phone with Qatari Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani on Saturday to discuss the situation in Syria, Turkish Foreign Ministry sources said.
He also spoke with Lebanese caretaker Prime Minister Najib Mikati.
