Israeli warplanes bombarded eastern and southern Lebanon on Monday as a UN-required truce between Israel and Lebanese Hezbollah guerrillas was due to take effect at 8 a.m. (0500 GMT).

Israeli warplanes attacked a village in eastern Lebanon, leaving two people dead and nine wounded, security officials said.

And the air-strikes on the edge of the Ein el-Hilweh refugee camp in the southern city of Sidon killed one person and injured three others, all of them civilians.

The raids came hours before a UN-brokered truce that was approved by the Israeli and Lebanese governments, as well as Hezbollah, on Sunday.

Israel's Haaretz newspaper reported on its Web site on Monday that Prime Minister Ehud Olmert had ordered his army to observe the truce from 2 a.m. on Monday (2300 GMT Sunday) and to start withdrawing some of its troops in south Lebanon.

But Israeli air strikes went on despite the ceasefire order.

The fighting between Israel and Hezbollah has entered its 33 days on Monday, leaving over 1,000 people dead.
