Israel is "exacting a heavy price from terrorist-supporting regimes" outside of its borders, Prime Minister Benjamin Netanyahu told his cabinet in televised remarks on Sunday, without elaborating.
The remark followed what Syria described as an Israeli military strike in Homs province and which, according to Western intelligence sources, hit air bases hosting Iranian personnel.
Israel has for years carried out attacks against what it has described as Iran-linked targets in Syria, where Tehran's influence has grown since it began supporting President Bashar al-Assad in the conflict that began in 2011 following a brutal crackdown of peaceful demonstrators.
Israel has intensified strikes in the last year on Syrian airports and air bases to disrupt what it says is Iran's use of aerial supply lines to deliver arms to militias.
Western intelligence sources have said Iran is increasingly using several civilian airports to deliver more arms, taking advantage of heavy air traffic as cargo planes offload relief aid following February's deadly earthquake.
