In the second such spy plane flight since November, the Mirsad drone overflew settlements in the north of Israel, a Hizb Allah source said on Monday. "It returned safely to base," he said.

  

After the mission, Israeli warplanes flew at low altitude over the southern port city of Tyre, causing a sonic boom, Lebanese police said.

   

And an Israeli naval boat patrolled the coast from the border town of Naqura to nearby Tyre, inside Lebanese territorial waters, the police said.

 

It was the second announcement by Hizb Allah since a first flight of a spy plane sent by the group over Israel in November.

  

That incident deeply embarrassed the Israeli air force, which has prided itself for decades on having total control of the region's skies.

  

Hizb Allah said the drones were retaliation for repeated Israeli violations of Lebanese airspace and warned that the spy planes could carry explosives to strike targets deep inside Israel if the latter attacked Lebanon.
