BAGHDAD (AFP) - Iraq criticised as "inappropriate" on Wednesday comments by US commander General Raymond Odierno accusing Iran of trying to bribe Iraqi MPs to derail a planned military pact with Washington. "The Iraqi government expresses its deep concern after the statements attributed to General Raymond Odierno," said government spokesman Ali al-Dabbagh, describing the remarks as "inappropriate."  "These kind of remarks are likely to tarnish the good relations between Iraq and the forces of the international coalition." Odierno had said in an interview published by the Washington Post on Monday that Iran was working publicly and covertly to undermine the planned Status of Forces Agreement between Baghdad and Washington that would provide the legal basis for a US troop presence beyond this year. US military spokesman Rear Admiral Patrick Driscoll said on Wednesday that Odierno's comment were not meant to infer that any Iraqi officials had accepted bribes. "The Council of Representative members work hard to represent and serve the Iraqi people performing an honourable, critical role in building the new Iraq," he said. Iraqi Prime Minister Nuri al-Maliki's spokesman Yasin Majeed said on Wednesday that top officials were considering a new draft of the proposed Status of Forces Agreement with a view to forwarding it to parliament. But he added that the discussions were likely to continue into the first half of next week and that further changes were likely. "We cannot say it is a final draft," he said. Meanwhile, the Iraqi army unearthed a mass grave near Karbala believed to contain the bodies of 22 shepherds kidnapped last year by Al-Qaeda, security and hospital sources said on Wednesday. "The military was conducting a search operation in the area when they found the mass grave containing 22 corpses in an area near Karbala," a security official told AFP.  Meanwhile, the US military claimed on Wednesday that a foreign insurgent killed in Mosul this month has been identified as Abu Qaswarah, Al-Qaeda's number two in Iraq. "Abu Qaswarah, also known as Abu Sara, was the Al-Qaeda in Iraq senior leader of northern Iraq," it said in a statement. It said Abu Qaswarah, a native of Morocco who was killed in a raid on a building in Mosul on October 5, had ties to Al-Qaeda in Iraq's (AQI's) founder Abu Musab al-Zarqawi, who was killed in a US air strike in Iraq in June 2006. "He was responsible for organising and leading Al-Qaeda in Iraq efforts in northern Iraq, including operations against Iraqi and coalition targets in Mosul." The US military also said Abu Qaswarah had trained with Al-Qaeda in Afghanistan and been in contact with senior leaders of the group's wing in Pakistan. He directed the movement of foreign fighters into northern Iraq, a position which he took up in 2007, it said. There was no independent confirmation of the report. The capture of Abu Qaswarah would undermine the insurgent group's capabilities, the US military said. "His death will significantly degrade Al-Qaeda in Iraq operations in Mosul and northern Iraq, leaving the network without a leader to oversee and coordinate its operations in the region." The US raid on a Mosul building which apparently served as a command and control centre for Al-Qaeda also led to the death of four other insurgents as well three women and three children, the military said in an earlier report. "As coalition forces entered the building housing the terrorist, they began receiving small-arms fire. Coalition forces returned fire once engaged," it said.
