Israel attacked dozens of Iranian targets in neighboring Syria this week in response to what it says was an Iranian rocket barrage, in the most serious military confrontation between the two bitter enemies to date.
The attack, if confirmed, would mark the first time Iran has fired rockets in a direct strike on Israeli forces. Thunderclaps of Israeli artillery fire reverberated across the frontier between Syria and Israel, with the faint sound of impact echoing back moments later.
Qasem on Friday also condemned the worldwide community's silence over Israel's attacks in Syria.
He said Iran would attempt to save the nuclear deal through negotiations with the European nations who were co-signatories to the deal.
Zarif made no mention of the flare-up with Israel, but said the country had the right to defend itself, particularly in the light of the eight-year war with Iraq that began when the regime of Saddam Hussein invaded Iran in 1980.
The Israeli military had no comment. It said three people were killed and two were wounded. "The Iranians declare their intention to attack us". According to the Israeli army, last night's strikes targeted Iranian-backed intelligence centers, weapons storehouses and logistics centers in Syria, as well as the rocket launcher that carried out the missile attack on Israel.
The Israeli strikes came after Iranian rocket attack strikes on the Israeli-held Golan Heights. Israel accuses Tehran of seeking to establish a foothold on its doorstep, something it has vowed never to allow.
U.N. Secretary-General Guterres is urging an immediate halt to "all hostile acts" to avoid "a new conflagration" in the Middle East after Israeli forces bombed Iranian targets inside Syria.
Israel's defense minister, Avigdor Lieberman, told a security conference that Israel struck "almost all the Iranian infrastructure in Syria".
"They need to remember the saying that if it rains on us, it'll storm on them". He added that he hoped Israel's action had ended the conflict and "everyone understood".
"Wherever Iran has confronted its enemies, it has advanced; we have gained our power through hard battles", said Brig.
"But we did say after the (Western) strikes (on Syria) that of course Russian Federation reserved the right to do anything it considered necessary".
Israel captured the Golan Heights in the 1967 war and annexed it in 1981. In addition, Israel launched more than 10 surface-to-surface tactical missiles on Syria, it said.
Later, in the early hours of the morning, explosions were heard in Damascus, while live images were broadcast on TV showing projectiles above the Syrian capital and several missiles destroyed by anti-aircraft systems.
Russia's Foreign Minister Sergey Lavrov was also quick to call for restraint.
They are allied with Russian Federation in efforts to fight off US -backed rebels and Islamic militants Iran is as unapologetic as Israel, voicing a refusal to "disarm ourselves against our enemies".
At the same time, Iran has covertly shipped missiles into Syria, according to the US.
The strikes came after 20 rockets were fired at Israeli military positions in the occupied Golan Heights overnight. Warning sirens were sounded in some Israeli communities in the Golan Heights.
One clear danger is that Iran may seek to exact its revenge outside the Middle East. They describe the claim that the historic attacks were in retaliation as being based "on self-proclaimed, baseless pretexts".
