On 24 November 2007, US military officials accused an Iranian special group of placing a bomb in a bird box that blew up at a popular animal market in central Baghdad. "The group's purpose was to make it appear Al Qaeda in Iraq was responsible for the attack", Admiral Smith said. He further emphasized there was "no evidence Iran ordered the attack". In May 2008, Iraq said it had no evidence that Iran was supporting militants on Iraqi soil. Al-Sadr spokesman Al-Ubaydi said the presence of Iranian weapons in Iraq is "quite normal," since "they are bought and sold and any party can buy them."
