A Lebanese crowd broke into the UN headquarters in the Lebanese capital on Sunday following a deadly Israeli air raid which killed more than 50 people in south Lebanon.

The crowd threw stones at the office in the heart of Beirut, and some of them broke into the building, a local television said.

Lebanese parliament head Nadia Berri told the pan-Arab al- Jazeera television that it was imperative for the United Nations to ask for a ceasefire and form an investigation committee to probe the killing in the southern Lebanese village of Qana.

Earlier, Israeli aircraft attacked Qana, which Israel terms as Hezbollah's rocket launch site, and killed more than 50 people, most of them children and women.

Lebanese Prime Minister Fouad Seniora condemned the Israeli airstrike, saying "such a heinous crime against our civilians will not break the will of the Lebanese people."

Israel launched its military offensives against Lebanese Hezbollah on July 12 in response to the group's capture of two Israeli soldiers in a cross-border attack.

More than 600 Lebanese and more than 50 Israelis have been killed in the fighting.
