Iranian President Hassan Rowhani has postponed Wednesday's and Thursday's planned state visit to Austria because of security reasons, the Austrian presidential office announced.
An Austrian official source told dpa on Tuesday that Rowhani's decision was likely tied to last week's terrorist attacks in Brussels, which have led to heightened security alert levels across Europe.
Austria had assured Iran that it could guarantee for Rowhani's security, the source added.
Rowhani had been scheduled to visit Vienna until Thursday to meet Austrian President Heinz Fischer and other Austrian leaders.
The Iranian president also postponed a trip to Baghdad for security reasons on short notice, Austria's presidential office said. That trip was supposed to last from Sunday to Tuesday, ahead of the visit to Austria.
