Ahmadinejad, in Iraq, Chides Bush on Iran Criticism.

President Mahmoud Ahmadinejad of Iran, arriving in Baghdad to open what he declared a ''new chapter'' in relations between Iraq and Iran, warned President Bush on Sunday that America's problems in the Middle East would worsen as long as he continued to accuse Iran of interfering in Iraq. The visit, the first by an Iranian leader since the brutal Iran-Iraq war of the 1980s, set off protests in Sunni Arab areas that seemed to underscore how growing Iranian influence could thwart hopes of mending the Iraqi government's sour relationship with Sunnis inside its own borders. Many of Iraq's Shiite leaders have ties to Iran. [ABSTRACT FROM PUBLISHER]
