The United Nations top human rights body has appointed a three-person panel to investigate possible Israeli human rights violations in Lebanon.

The U.N.'s Human Rights Council appointed the panel to look into what it calls Israel's "systematic targeting" of civilians during the month-long offensive against Hezbollah. The panel also will examine whether Israel violated international law in the type of weapons it used.

The panel members are a Tanzanian judge, a Brazilian diplomat and a Greek professor.

Israel used cluster bombs, among other weapons, in attacking Hezbollah-controlled areas of southern Lebanon.

In other news, a senior U.N. official, Humanitarian Coordinator in Lebanon David Shearer, said Friday that unexploded Israeli munitions are the second major challenge for Lebanon, after reconstruction.

The United Nations says around 100,000 cluster bomblets are unexploded and pose a serious danger to Lebanese civilians.

Israel says it did not violate international laws on the use of weapons.
