(AP) — An opinion piece published Sunday by a hard-line Iranian newspaper urged Iran to attack the Israeli port city of Haifa if Israel carried out the killing of the scientist who founded the Islamic Republic’s military nuclear program in the early 2000s.

Though the hard-line Kayhan newspaper has long argued for aggressive retaliation for operations targeting Iran, Sunday’s opinion piece went further, suggesting any assault be carried out in a way that destroys facilities and “also causes heavy human casualties.”

Israel, suspected of killing Iranian nuclear scientists over the past decade, has not commented on the brazen slaying of Mohsen Fakhrizadeh. A military-style ambush Friday on the outskirts of Tehran reportedly saw a truck bomb explode and gunmen open fire on the scientist, killing him and a bodyguard.

U.S. intelligence agencies and U.N. nuclear inspectors have said the organized military nuclear program that Fakhrizadeh oversaw disbanded in 2003. Israel insists Iran still maintains the ambition of developing nuclear weapons.

Kayhan published the piece written by Iranian analyst Sadollah Zarei, who argued Iran’s previous responses to suspected Israeli airstrikes that killed Revolutionary Guard forces in Syria did not go far enough to deter Israel. READ MORE
