The incident was reported after the Israeli combat helicopter came in contact with an Iranian unmanned aerial vehicle that had been launched from Syria, the Israel Defence Forces (IDF) said in a statement.
The two pilots parachuted to safety before the crash.
Israeli forces also launched attacks on what they described as Iranian targets in Syria, the IDF said.
"The IDF is striking numerous (12) Syrian and Iranian military targets in Syria, in response to Iranian aggression. More to follow," he said in another tweet.
