(CNN) -- Syria accused Israel of a "flagrant violation" of its obligations when it carried out an airstrike inside the country last week, according to a copy of a letter released Tuesday.
Israeli soldiers deployed in the Golan Heights look toward Syria on September 7.
Syria called the incursion a "breach of airspace of the Syrian Arab Republic" and said "it is not the first time Israel has violated" Syrian airspace, the letter to U.N. Secretary-General Ban Ki-moon read.
It also accused the international community of ignoring Israeli actions.
Earlier, a U.N. spokeswoman said Syria had not requested a meeting of the Security Council.
Meanwhile, France -- the current president of the Security Council -- said it had received no letter from Syria.
Last week, Syria reported that its aircraft fired on Israeli "enemy aircraft" that flew into northern Syria early Thursday.
The airstrike may have targeted weapons that were destined for Hezbollah militants, according to sources in the region and in the United States. Watch a report on the airstrike »
The Israel Defense Forces had no comment on the report, and have refused to comment further on the new revelations.
But the sources told CNN the military operation, which happened Wednesday into Thursday, may have also involved Israeli ground forces who directed the airstrike, which "left a big hole in the desert" in Syria.
The strike may have targeted Hezbollah weapons coming into Syria or transiting through the country from Iran -- a pattern that, over the past three or four years, has occurred without any retaliation or other action taken against it -- the sources said.
The Israeli government is very happy with the success of the operation, the sources said.
Sources in the U.S. government and military confirmed to CNN's Barbara Starr that the airstrike did happen, and that they are happy to have Israel carry the message to both Syria and Iran that they can get in and out and strike when necessary.
Right now, diplomats in the region are trying to ensure the incident does not escalate.
The European Union's foreign policy chief, Javier Solana, is serving as a conduit between Israeli and Syrian foreign ministers, urging both sides to allow cooler heads to prevail, Solana's office said.
Syrian Foreign Minister Walid al-Moualem and other Syrian officials have been putting out their version of events. The Syrian government said Israeli bombs were dropped on its territory and fuel tanks from Israeli jets were dropped on the Turkish side of the border.
Al-Moualem was in the Turkish capital, Ankara, on Monday protesting this action and trying to get Turkey to support its desire to take Israel to the Security Council for the airstrike.
Israel fought a war with Hezbollah guerrillas in southern Lebanon last year after Hezbollah captured two Israeli soldiers, who are still being held. E-mail to a friend
