Two warplanes twice flew low over Beirut, police said, with four planes carrying out similar mock raid over southern Lebanon, causing a sonic boom over the port city of Tyre, as Muslims celebrated the end of Ramazan.
"These are the most intensive overflights since August 14 ... and it looks like another defiance of 1701 and of French appeals," a police source said, referring to UN Security Council Resolution 1701 that ended the 34-day war.
The territorial violations came days after France, which currently leads the UN peacekeeping force in south Lebanon, said it might open fire on the intruding aircraft.
Israeli Defence Minister Amir Peretz vowed on Sunday that the flights would continue because of alleged arms smuggling to Hizbullah since the August 14 end of the group's summer war with Israel.
"Increasing intelligence indicates a growing effort to pass weapons into Lebanon," Peretz said, accusing the Lebanese government of failing to prevent arms smuggling as required by Resolution 1701.
"As long as these attempts continue, the legitimacy of our flights over Lebanon increases," Peretz said. "As long as Resolution 1701 is not carried out, we have no intention of stopping the flights over Lebanon."
The flights have been increasingly criticised by the international community, with France warning on Friday against the violations.
"These violations are extremely dangerous because they may be felt as hostile by forces of the coalition that could be brought to retaliate in case of self-defence," French Defence Minister Michele Alliot-Marie said.
Resolution 1701 calls for the disarming of all militias in Lebanon, the withdrawal of Israeli troops from the south of the country, and the deployment of a beefed-up UN peacekeeping force.
