"The landing carried out by Israeli occupation forces today in the Bekaa was a flagrant violation of the cessation of hostilities announced by the Security Council," Seniora said in a statement.

He said that he had complained to a UN delegation Saturday, and would take up the matter with UN chief Kofi Annan.

The Israeli army confirmed that Israeli commandos carried out a raid on a Hezbollah stronghold near the Bodai village in eastern Lebanon early Saturday to prevent weapons from being transferred to Hezbollah from Iran and Syria.

The army said that one officer was killed and two others wounded in the raid.

It was the first Israeli raid deep inside Lebanon since a ceasefire between Israel and Hezbollah came into effect on Monday under a UN Security Council resolution.

The truce ended the 33-day-long Israel-Hezbollah conflict, which was triggered by the capture of two Israeli soldiers by Hezbollah in a cross-border raid on July 12.
