Lebanon warns against truce violations

"Any violation... any rocket that would give Israel a justification (to hit Lebanon) will be treated harshly," Murr told a press conference.

"It will be considered as direct collaboration with the Israeli enemy," Murr said, adding that those responsible "will be tried and referred to a military tribunal."

He was referring to a UN-brokered ceasefire that came into effect on Monday to end 34 days of warfare between Israel and the Shia Muslim Hezbollah that left around 1,400 people dead, mostly Lebanese civilians.

Murr said that Hezbollah "is totally committed to this, so there are no fears."

"When the Resistance (Hezbollah) is committed not to fire rockets, any rocket that is fired from Lebanese territories will be considered a direct collaboration with Israel," he said.

"When the Resistance is committed, any violation will be in favor of Israel," he said.

Murr said Lebanese troops will complete over the next few weeks their first deployment in four decades in southern Lebanon and along the borders with Syria.

The UN resolution that led to the ceasefire calls for Israeli troops to withdraw from south Lebanon in tandem with the deployment of the Lebanese army and a strengthened UN force of 15,000 troops.

Earlier Lebanese Prime Minister Fuad Siniora on Sunday accused Israel of committing crimes against humanity during its month-long offensive on his country.

"This is a criminal act which reflects Israel's hatred to destroy Lebanon and its unity," he said during a tour of Beirut's bombed-out southern suburbs with parliament speaker Nabih Berri.

"I hope all the international media will transmit this picture to every person in the world so that it shows this criminal act, this crime against humanity that Israel has committed in this area and every region of Lebanon."

Siniora was speaking as a fragile UN-brokered truce to end the conflict between Israel and Hezbollah entered its seventh day. Close to 1,300 people in Lebanon were killed and billions of dollars in damage caused to homes and infrastructure such as bridges and roads.

"We will not allow the Israeli enemy... to destroy our national unity," said Hezbollah MP Ali Ammar who met Siniora and Berri during their tour of the southern suburbs, a stronghold of the Shia Muslim group.
