* Israel loath to clash accidentally with Moscow's forces

HERZLIYA, Israel, Sept 8 (Reuters) - Indications of increased Russian involvement in Syria in support of President Bashar al-Assad are prompting a reassessment in Israel about how to handle fall-out from the conflict without risking a clash with Moscow.
Since the Syrian civil war began in 2011, Israel has occasionally fired across the Golan Heights in response to spillover shelling or bombed advanced arms it suspected were to be transferred to Assad's Lebanese guerrilla allies, Hezbollah.
U.S. and regional reports that Moscow's diplomatic and logistical support for Assad is shifting into major military backing has raised the prospect of Israel and Russia accidentally coming to blows.
"There could be ramifications for us, certainly," Ram Ben-Barak, director-general of Israel's Intelligence Ministry, told Reuters when asked if Russian intervention in Syria might necessitate new Israeli rules of engagement.
He was speaking at a security conference organised by the Herzliya Interdisciplinary Center, where Russian policy in Syria was described both as an effort to shore up Assad and mobilise with other world powers in suppressing Islamic State insurgents.
"We have been informed that the Russians are entering into active intervention, the Americans are attacking ... The West and now, in fact, the Russians and the whole world are trying to unite against them (Islamic State)," Amos Gilad, senior adviser to Israeli Defence Minister Moshe Yaalon, said in a speech.
In separate remarks to Reuters, Gilad said it was too early to know how extensive Moscow's military involvement in Syria would be and whether it might clip Israel's wings operationally.
"I don't know, because the scale is not yet clear. They haven't started working. They are just building up the capability," Gilad said of the Russian activity.
Asked if Israel was communicating with Russia in a bid to head off any unintended confrontations between their forces, he said only: "There are ways. They are not our enemies today."
In Moscow, the Foreign Ministry spokeswoman said she had no information about any communication between Israel and Russia.
Israel has sought to stay out of the Syrian civil war, seeing enemies on all sides. It says it intervenes militarily only when fired upon from Syria or to prevent Hezbollah operatives reinforcing Assad there from gaining advanced weapons that could pose a threat to it from Lebanon in the future.
Past Israeli strikes in Syria killed Syrian troops as well as Hezbollah fighters, according to both countries and the guerrilla group - though the exact number remains unclear.
In recent days, Moscow has reaffirmed its military backing for Damascus but said it was premature to talk about Russian participation in military operations in Syria.
U.S. authorities have detected "worrisome preparatory steps", including transport of prefabricated houses for hundreds of people to a Syrian airfield, that could signal Russia is readying for deployment of heavy military assets, a senior U.S. official told Reuters last week.
Syria has not formally responded to the reports. But one of its military officials has spoken of a "big shift" in Russia's military support for Damascus.
Amos Yadlin, an Israeli air force ex-general and Prime Minister Benjamin Netanyahu's former military intelligence chief, said Israel and Russia were unlikely to find themselves pitted against each other in Syria as they had different areas of interest.
"I don't think there is any reason for the sides to collide, as we are not fighting the same enemy. I assume that we will be very careful, and so will they," said Yadlin, now director of Tel Aviv University's Institute for National Security Studies.
He predicted Russian forces would avoid the Golan, near Israel's northern front, and Israel would think twice about carrying out air strikes where Russians might be harmed.
"My assumption is that we don't attack any site on the ground in Syria unless we have an excellent picture of who is or isn't there," Yadlin said.
A senior U.S. official briefed on Israel's actions in Syria shared Yadlin's assessment, but cautioned: "Nothing is fool-proof, so I can anticipate the Israelis will be looking anew at their risk-assessments now."
Syria's ageing air force is largely Soviet-supplied, posing a possible scenario where similar models of jets and choppers could be flown by local and Russian pilots.
Sam Gardiner, a retired U.S. air force colonel who runs wargames for various Washington agencies, said Israel would likely be able to spot Russian-operated aircraft in good time.
"Russian aircraft would probably have a different 'signature' - even if they're the same airplane they wouldn't be equipped with the same electronics," he said, theorising that the Israelis would know which Syrian airbases were being used by Russia and be able to trace Russian-language radio communications to the jets or helicopters they came from.
