Speaking at the general debate of the UN General Assembly, Ahmadinejad spared no words in attacking the occupation of countries and exacerbation of hostilities by the United States in the Middle East.

"Not a day goes by without hundreds of people getting killed in cold blood," he referred to the U.S. occupation of Iraq, saying "there is no indication that the occupiers have the necessary political will to eliminate the sources of instability."

The occupiers were incapable of establishing security there which affected the entire region, Ahmadinejad said, adding intensification of hostilities and terrorism served as a pretext for the continued presence of foreign forces in Iraq.

On the situation in the Palestinian territories, the Iranian president vehemently accused Israel of being a constant source of threat and insecurity in the Middle East region, arguing Israel had been used by some powers as an instrument of division, coercion and pressure on the people of the region.

Citing the abduction of some Palestinian officials by Israel, he criticized the UN Security Council for failing to protect the "brutally besieged government."

"People are being bombarded in their own homes and their children murdered in their own streets and alleys. But no authority, not even the Security Council, can offer them any support or protection," Ahmadinejad added.

On the recent situation in Lebanon, he said for 43 days, the Lebanese lived under the barrage of fire and bombs and close to 1.5 million of them were displaced while the Security Council sat idly by, witnessing the cruel scenes of atrocities against the Lebanese.

"The Security Council was practically incapacitated by certain powers to even call for a ceasefire," Ahmadinejad said, obviously pointing to the United States.
