Israeli warplanes struck a military base near the Syrian port city of Latakia this week, an Obama administration official said.
An explosion occurred at a missile storage site in Latakia, but an attack has not been confirmed by the Israeli government.
According to CNN, the official said that the target was missiles and related equipment that were targeted by the Israel, as the country felt might be transferred to the Lebanon-based militant group Hezbollah.
Israel has been accused several other times this year of launching airstrikes inside Syria, including once in January.
In the January incident, a U.S. official said Israeli fighter jets bombed a Syrian convoy suspected of moving weapons to Hezbollah, the report added.
