The US military has claimed that about 50 Iraqi fighters were wounded in a failed attempt to enter the infamous Abu Ghraib prison west of Baghdad. Al-Qaida in Iraq posted a second Internet statement boasting that its fighters carried out the bold attempt on Saturday to force their way into the prison. The statement said two fighters were injured and 10 more were killed in battle, including seven bombers. The statement was impossible to independently verify, and it conflicted with the US account of the assault. US military officials said on Monday that only one bomber was used in Saturday's attack, along with gunfire, mortar rounds and rocket propelled grenades. At least one fighter was killed. More than 40 US service members and 13 prisoners were injured in the attacks.
