A senior Iranian official on Wednesday warned that if Israel attacks Iran's embassy in Lebanon, all its embassies will become legitimate targets, according to the semi-official Tasnim news agency.

Abolfazl Shekarchi, a spokesman for Iran's armed forces, made the remarks in reaction to Israel's recent threat against Iran's embassy in Lebanon.

Shekarchi stressed, "If Israel commits such a crime and targets Iran's embassy in Lebanon, it will force us to consider all Israeli embassies across the world as legitimate targets, and we will definitely take countermeasures."

Shekarchi said that except for the United States and Israel, Iran has no hostility toward other countries and advances its foreign relations based on engagement.

The remarks came as the joint U.S.-Israeli military operation against Iran entered its fifth day. The operation has triggered a sharp escalation across the Middle East, setting off waves of missile exchanges, mounting casualties, and far-reaching political, security, and economic repercussions.
