JERUSALEM, Israel -- GOP Sen. John McCain said Israel's second airstrike Sunday in Syria could be the incentive President Obama needs to take action in the wartorn country.
"We need to have a game-changing action, and that is no American boots on the ground, establish a safe zone and to protect it and to supply weapons to the right people in Syria who are fighting, obviously, for the things we believe," the Arizona lawmaker told "Fox News Sunday."
Meanwhile, Syrian Deputy Foreign Minister Faisal al-Mekdad said the Israeli airstrikes constitute a "declaration of war."
Mekdad told CNN Sunday the airstrikes prove that Israel has allied itself with Islamist rebels trying to bring down the government, warning that Syria would retaliate in its own way and own time.
The Foreign Ministry in Damascus said the attacks aimed "to give direct military support to terrorist groups" fighting President Bashar al-Assad's government.
The Syrian Foreign Ministry made similar threats last year when Israel struck a weapons convoy near the Lebanese-Syria border.
Mekdad filed a complaint with the United Nations, with Lebanon saying it will also file a complaint against Israel's "repeated violations" of its airspace.
Syrian officials claim Israeli rockets struck the site, destroying Iranian-made Fateh 110 missiles to be delivered to the Lebanese-based Hezbollah terror organization.
"In last night's attack, as in the previous one, what was attacked were stores of Fateh-110 missiles that were in transit from Iran to Hezbollah," Reuters quoted a Western intelligence source.
Israel had no immediate comment, with an Israel Defense Forces (IDF) spokeswoman telling Reuters, "We don't respond to this kind of report."
On Saturday, an unnamed Israeli government official confirmed an Israeli airstrike on a Syrian missiles shipment headed to Hezbollah guerrillas in Lebanon, Reuters reported. No chemical weapons were targeted.
Prime Minister Benjamin Netanyahu approved the strike Thursday in a secret meeting with his security cabinet, the official added.
Earlier, CNN's Jerusalem-based correspondent, Sara Sidner, quoted an Israeli defense official saying "We will do whatever is necessary to stop the transfer of weapons from Syria to terrorist organizations. We have done it in the past and we will do it if necessary in the future."
