Lebanese caretaker Foreign Minister Adnan Mansour on Sunday urged the Arab League (AL) to take a \" decisive stance\" toward the recent Israeli airstrike on Syria. Mansour accused Israel of pushing the region to \"a destructive confrontation,\" urging the AL to be decisive to \"avoid further escalation.\" Israel allegedly targeted a military research center in an area northwest of Damascus overnight Saturday that housed an Iranian missile shipment for Hezbollah in Lebanon, a main ally to Syria. The airstrike was the second Israeli one targeting the same facility after one in January. Israel said then that it was targeting a weapons convoy on its way to Hezbollah. In the early hours of Sunday, the Israeli army raised the degree of mobilization along the Lebanese border, with warplanes, helicopters and reconnaissance planes intensively flying over Shebaa farms, Arqoub, the Bekaa valley and many other Lebanese regions. The UN Interim Force in Lebanon and truce monitors also intensified their patrols along the Blue Line, drawn in 2000 following the withdrawal of Israeli forces from Lebanon.
