The Israeli army was placed on high alert along the border with Lebanon and in Syria's occupied Golan Heights, the Israeli Radio reported early Sunday.
The move was taken over the possibility of an escalation in the region on the eve of Eid al-Fitr, marking the end of the holy Muslim month of Ramadan, and in the light of the ongoing military onslaught in the Gaza Strip, the broadcaster quoted an unnamed military source as saying.
There have been several incidents of rockets fired from South Lebanon into Israel, including the latest Friday that fell short of its target and landed in Lebanon, since the beginning of the Israeli war on Gaza 20 days ago. The Israeli army has responded with artillery fire into South Lebanon.
Army troops stationed across the Gaza Strip have also taken measures over the possibility of another outbreak of violence against the background of the military offensive in Gaza, he added.
Israel has launched a devastating military offensive in the Gaza Strip with the ostensible aim of halting rockets.
More than 1,000 Palestinians have been killed and 6,000 injured in the Israeli assault.
A 12-hour temporary truce Saturday brought attacks to a halt, with Israel extending the ceasefire until midnight Sunday. Gaza-based Palestinian factions, however, have rejected the extension of the ceasefire, continuing to fire rockets at Israel.
At least 46 Israelis - 43 soldiers and three civilians - have also been killed since hostilities began.
