Israel said it would not allow advanced weapons to fall into the hands of Hezbollah, after reports it had attacked a Syrian air base holding missiles for the militant group.
Israel declined to comment on media reports that its planes had hit the base near the port of Latakia.
However, Home Front Defence Minister Gilad Erdan told Israeli radio: "We have said many times that we will not allow the transfer of advanced weapons to Hezbollah. We are sticking to this policy and I say so without denying or confirming this report."
