Iranian Foreign Minister Mohammad Javad Zarif was supposed to meet Alexander Schallenberg but had called off the trip, a spokeswoman for Schallenberg said, confirming a report in newspaper Die Presse.
"We regret this and take note of it, but for us it is as clear as day that when Hamas fires more than 2,000 rockets at civilian targets in Israel then we will not remain silent," the spokeswoman said.
State media said a plastics factory was among the sites hit in the raids, which struck the towns of Hifa in Latakia and Masyaf in the neighbouring province of Hama.
