Police updated the death toll from seven to nine Lebanese soldiers following a raid on a military intelligence base north of Tripoli, which wounded 10 others.
A further 44 people were injured other the attacks, notably in Baalbeck as well as Tripoli according to police.
Israeli jets also launched nine raids in less than a quarter of an hour on the town of Baalbeck, a bastion of Hezbollah, killing three civilians and wounding six others.
The bombing raids also targeted seven petrol stations and several Hezbollah buildings including a commercial cooperative and a school, police said.
The Lebanese Red Cross said that further south, two civilians were killed and 12 injured when three Israeli missiles landed on homes in the village of Jalala in the Zahle region in eastern Lebanon.
South east of Beirut three civilians were killed just before midnight when Israeli air raids hit a house in the Chouf mountains region, police said.
At dawn on Monday Israeli airforce planes blew up the last two oil reserves at Beirut's closed international airport. One soldier was injured hours earlier when a missile hit the airport tarmac.
Hezbollah attacks
Hezbollah fired rockets fired from Lebanon that have struck deeper into Israel than ever before, hitting the town of Afula about 50 kilometres south of the border, the Israeli army said.
According to the army, rockets also landed on the outskirts of the holy city of Nazareth and in other nearby towns and villages. There were no immediate reports of casualties.
Twelve Israeli civilians have been killed from Hezbollah rockets, including eight in Haifa, according to the BBC.
Israeli Prime Minister Ehud Olmert said the Haifa attack - the worst on Israel since clashes started - would have "far-reaching consequences".
Canadians death toll revised
The Canadian government have revised the death toll of an Israeli attack in the south of Lebanon on Sunday that killed a number of civilians with Canadian and Lebanese citizenship.
Earlier, Foreign Minister Peter MacKay said that eight Canadians had been killed and a spokeswoman for the department later confirmed that only seven Canadians were killed and three wounded.
Spokeswoman Ambra Dickie said that the Canadian ambassador in Lebanon was in contact with the families of the victims.
Ms Dickie did not confirm reports that at least five of the victims were related or that they may have been killed in the same Israeli air raid.
According to Lebanese police, five of the dead were from the same family, killed in an Israeli air attack, which hit their home near the Israel-Lebanon border.
Civilian deaths
The Israeli air strikes began after Hezbollah seized two Israeli soldiers in a raid into Israel on Wednesday.
Both AFP and Reuters news agencies estimates that more than 150 people have died since clashes with Israel began on Wednesday Reuters has reported that all but 13 of them were civilians.
AFP’s tally has been compiled on the basis of reports from officials and hospital staff, which have also established that more than 355 people have been wounded since the start of the offensive.
Nineteen civilians died in an Israeli attack on a building housing a military office and transmitter in the southern port town of Tyre, hospital sources said. They had been seeking shelter after fleeing Israeli raids on their home villages.
Israel has pressed on with its attacks despite having said it regretted causing civilian casualties, blaming Hezbollah operations in populated areas for the collateral deaths and injuries.
Twenty-four Israelis have been killed in the violence, according to AFP. 12 civilians and 12 soldiers have died in Hezbollah rocket attacks.
Who is to blame?
Russian and US officials are at loggerheads over whether Damascus and Tehran lay behind the Hezbollah attacks.
The US insists that Syria and Iran have some responsibility for the attacks by the Lebanese militia, but Russian Foreign Minister Sergei Lavrov says that there is no evidence to back up the allegation.
"Well, I have heard this speculation. I've also heard speculation that Syria and Iran are involved in staging terrorist attacks. We take this very seriously, but we want to see facts," Mr Lavrov told CNN.
"We would be last to ignore the facts of this type of involvement," Mr Lavrov said. "But so far we haven't seen any proof."
However, US Secretary of State Condoleezza Rice insisted that Syria and Iran were directly involved.
"I absolutely see that Syria and Iran are playing a part in this. They're not even trying to hide their hand," she told CBS television.
"Syria has held press conferences with radical elements of Hamas," she said, mentioning the radical group controlling the Palestinian government.
"They've held press conferences for Hezbollah. The radical elements of Hamas sit in Syria and find harbor there. And Iran is the major financier of these efforts."
Observers fear Israel may next target Syria and Iran and Israeli Vice Premier Shimon Peres has claimed that that Hezbollah fired missiles on northern Israel from Syria.
Syria has warned that any Israeli attack "will provoke an unlimited, direct and firm response using all means necessary."
Iran said it would stand by Syria and warned of "unimaginable losses" if Israel attacked.
