Iran reiterated Saturday its threats that any attack on Syria would be perceived as one on the Islamic Republic and will meet “a harsh response.”

Tehran’s IRNA news agency quoted Defense Minister Brigadier-General Ahmad Vahidi as saying that Syrian Army, which is “the vanguard of campaign against Zionist regime should not be weakened.” [...]

The threats have become more strident following NATO’s decision to send Patriot missile batteries to Turkey, which fears the civil war tearing its neighbor apart may morph into a war between them.

“The Syrian problems have roots in covert and overt interference of the Zionists,” he said adding that “Iran has always adopted a rational stand toward Syria.”
