The issue was announced by Iran’s embassy in Moscow on Tuesday.
The visit by Amir Abdollahian will take place as foreign-backed militants shell two mosques, a hospital and several neighborhoods in the northern Syrian city of Aleppo, killing dozens of people and injuring many others.
Over the past few days, foreign-backed militants have conducted rocket attacks on several government-controlled neighborhoods in Aleppo, leaving heavy casualties and a ceasefire deal in tatters.
Also on Tuesday, Russian Foreign Minister Sergei Lavrov told reporters after talks with UN envoy Staffan de Mistura in Moscow that a cessation of hostilities could be announced in Aleppo "in the next few hours."
"I am hoping that in the near future, maybe even in the next few hours such a decision will be announced,” Lavrov said
Several hospitals and clinics have previously been hit by deadly militant attacks in the embattled city.
