"Europeans are trying to exert political and diplomatic pressure on Iran for its response to Israel to be 'symbolic,' as they say, and to the extent that the Israelis want," he told the Almasirah broadcaster.
"However, the position of the Jerusalem axis aimed at resistance is clear: there must be a dangerous military response to the serious crimes and serious escalation by Israel. Weakness will only encourage it to commit new crimes."
On Wednesday, Hamas confirmed that its political leader, Ismail Haniyeh, had been killed in an Israeli attack on his residence in Tehran after he took part in the inauguration of newly elected Iranian president Masoud Pezeshkian.
Hamas has blamed Israel and the United States for Haniyeh's death and vowed to retaliate. Pentagon chief Lloyd Austin said he had nothing to say about Haniyeh's death or Israel's alleged role in it. The Jerusalem Post reported that the Israeli government had instructed ministers not to comment on Haniyeh's assassination.
On Tuesday night, the Israel Defense Forces (IDF) carried out a strike in a southern suburb of Beirut, killing Hezbollah commander Fuad Shukr.
