Regional leaders continued working on implementing a cease-fire to escalating conflict between militants in Hamas-controlled Gaza and Israel.
Andrea Tenenti, a spokesman for the U.N. Interim Force in Lebanon, told The Daily Star newspaper in Lebanon that the border area was stable.
"There are no tensions and we are continuing to work with the Lebanese army to avoid any aggression in the region," he said.
Israel maintains a defensive posture given the presence of Hezbollah along Lebanon's southern border. Beirut has complained repeatedly to the United Nations that the Israeli military violated its airspace with frequent overflights.
U.N. Security Council Resolution 1701 secured a cease-fire in a 2006 war between Hezbollah and Israel. The measure calls on Hezbollah to disarm while reminding Israel of its obligation to respect Lebanon's sovereignty.
Hezbollah Secretary-General Hassan Nasrallah said early this week that Israel would "face the consequences" should it decide to send ground forces into Gaza.
