Israel has carried out air strikes in the central and western parts of Syria, the country's state news agency said on Monday night.
Syria's Foreign Ministry condemned the air strikes as "a blatant infringement" of its sovereignty and regional stability, Reuters reported.
There was no immediate comment from Israel. Previously the defence minister Israel Katz said, "forces are operating in all combat zones day and night for the security of Israel".
Israel has carried out dozens of attacks across Syria after the fall of ex-President Bashar al-Assad in December, which saw an Islamist-led government set up by former rebels.
