"What I have said in the past and I continue to believe is that the Israelis justifiably have to guard against the transfer of advanced weaponry” to resistance movements like Hezbollah, Obama stated.
"We coordinate closely with the Israelis, recognizing that they are very close to Syria, they are very close to Lebanon," he added.
Earlier, Israel confirmed it carried out an aerial attack on Syria on Friday, claiming it targeted a shipment of "game-changing" weapons.
The Lebanese military also stated that pairs of Israeli warplanes entered Lebanese airspace three times overnight.
On January 30, the Syrian Army issued a statement saying that two people were killed and five others injured in an Israeli airstrike on a research center in Jamraya, which is located about 25 kilometers northwest of Damascus.
The Syria crisis began in March 2011, and many people, including large numbers of soldiers and security personnel, have been killed in the violence.
The Syrian government says that the chaos is being orchestrated from outside the country, and there are reports that a very large number of the militants are foreign nationals.
In addition, several international human rights organizations have accused foreign-sponsored militants of committing war crimes.
US President Barack Obama has said Israel has the right to launch airstrikes on Syria, one day after the Israeli regime's second airstrike on the country this year.
In an interview with the Spanish-language network Telemundo in San Jose, Costa Rica on Saturday, Obama stated that Israel has the right to protect itself from what he called advanced weapons shipments to Lebanon.
He said he would not comment on the veracity of the reports on the attack and would let the Israeli regime "confirm or deny whatever strikes that they've taken."
