IAF warplanes carried out a number of "mock raids" over Lebanese airspace on Friday night, Lebanon's official National News Agency reported.
According to the report, beginning at 9:30 p.m. on Friday, the IAF jets flew at low altitude over the towns of Nabatiyeh, Iklim al-Tuffah, Marjayoun and Bint Jbeil.
Lebanon frequently complains that Israeli jets overfly its territory.
Earlier this week, a Lebanese army statement said that four IAF warplanes entered Lebanese air space at 4.30 p.m on Tuesday. They were replaced four hours later by another group of planes which overflew southern Lebanon until 2 a.m and a third mission took over, finally leaving at 7.55 a.m on Wednesday morning.
The statement made no mention of planes entering Syrian airspace but shortly afterward reports emerged that Israeli jets had struck an arms convoy on the Lebanon-Syria border.
The Syrian SANA news agency released a statement by the General Command of the Armed Forces, which sought to link the supposed strike to Israel’s support – and that of other countries – for the Syrian rebels.
“Warplanes violated Syrian airspace on Wednesday at dawn and bombarded a scientific research center responsible for raising our levels of resistance and self-defense. This attack came after Israel and other countries that oppose the Syrian people utilized their pawns in Syria to attack vital military locations,” the statement said.
General Command also said that the attack “martyred” two workers and wounded five others.
The “research center” building was also destroyed. It went on to deny claims that the attack targeted a convoy headed for Lebanon.
