The Israeli military said its forces had captured several fighters before returning to their base without suffering any losses. Hizballah denied those detained belonged to the group.
Witnesses said Israeli air strikes in Baalbek killed at least 11 people.
AFP reports Israeli warplanes also destroyed two bridges in northern Lebanon, some 5 kilometers from Syria.
Meanwhile, Hizballah today fired dozens of rockets into northern Israel, wounding at least seven. A rocket hit the town of Beit Shean, almost 70 kilometers from the Lebanese border, the deepest a Hizballah-fired rocket has struck into Israel.
"If indeed, as we hope, the international force will be an effective force made of combat units, then we will be able to stop the fire when the military force -- international force -- will be on [the] ground in the south part of Lebanon," he said.
Olmert said he wants the peacekeepers to have a mandate to enforce a UN resolution calling for the disarmament of Hizballah. He said Israel has already destroyed much of the group's military capability.
Also today, an Israeli aircraft fired a missile at a Lebanese Army base in southern Lebanon, killing three soldiers.
Hizballah fired rockets at towns across northern Israel, but caused no casualties.
The fresh violence comes with Israel set to resume full air strikes in Lebanon after a partial 48-hour suspension following a raid on Qana. More than 50 people died in that Israeli attack, most of them children.
Israel's army said it has warned residents north of Lebanon's Litani River to leave the area, suggesting air raids could target areas farther north than most previous strikes.
The United Nations and Red Cross say they've been forced to delay the dispatch of aid to southern Lebanon because of a failure to get security guarantees.
On August 1, the EU called for an immediate halt to hostilities to be followed by a sustainable cease-fire.
The UN Environment Program (UNEP) today said a large oil slick in Lebanon could cause long-term environmental damage.
The slick was caused when Israeli warplanes struck storage tanks at a power plant south of Beirut in mid-July. It already covers one-third of the Lebanese coast.
Lebanon has requested international assistance. But Achim Steiner, UNEP's executive director, says hostilities make it impossible to begin the cleanup.
