JERUSALEM - Iran now commands a force of around 25,000 Shi'ite Muslim militants in Syria, mostly made up of recruits from Afghanistan and Pakistan, the former head of Israel's domestic intelligence agency has told a visiting Swiss delegation.
Avi Dichter, chair of Israel's foreign affairs and defense committee, told members of the Swiss parliament the Iranian-backed force was focused on fighting Sunni rebels opposed to Syrian President Bashar al-Assad, not Islamic State.
"This is a foreign legion of some 25,000 militants, most of whom have come from Afghanistan and Pakistan," Dichter told the delegation during the briefing on Wednesday, according to details provided by his office. "They are fighting in Syria only against the rebels and not against ISIS."
It was not clear what the source of Dichter's information was, but he receives intelligence briefings in his role.
In Syria, Iran also has the support of the Lebanese militia Hezbollah, which has long experience in the region, particularly against Israel. It is not clear how many Hezbollah fighters are in Syria, but Dichter said 1,600 had been killed.
"The Iranians enlisted Hezbollah ... to fight in Syria because the Iranian army is better suited to fight as an army against another army, while the Hezbollah militants are adept at fighting against terror groups," he said.
"The fighting has made (Hezbollah) a better fighting force and more adept in conventional military warfare."
The briefing covered the fallout from the conflict, including the flow of migrants and refugees to Europe. Dichter cautioned that European states should not be naive about who was attempting to enter their borders.
Israel has long seen Iran as its greatest threat and campaigned hard against US-led efforts to strike a nuclear deal with Tehran. At the same time, Israel frequently plays up the improving relations it has with some Sunni Arab states in the region, including Egypt and, to an extent, Saudi Arabia.
Dichter told the delegation that Iran's "dream" was to rule the Islamic holy sites of Mecca and Medina in Saudi Arabia.
"Everybody should ask themselves why the Iranians are building missiles with a range of 2,000 km, twice the distance (from their territory) to Israel," he said.
"Egypt is also within their range, as is Saudi Arabia. Two thousands years ago, Iran was an empire and now it wants to recreate that."
Echoing a common refrain from centre- and right-wing Israeli lawmakers, Dichter said that was why Israel was convinced Iran had not abandoned its nuclear aspirations but only put them on hold, playing a long game against the West.
