BAGHDAD -- Suicide bombers killed 13 people in a pair of attacks Monday around the Sunni city of Ramadi in what local officials said was part of a power struggle between al-Qaida and tribes that have broken with the terror network.
In all, at least 68 people were killed or found dead nationwide Monday, police said. They included the bullet-riddled bodies of 30 men found in Baghdad -- the apparent victims of sectarian death squads.
The power struggle among the Sunnis, which surfaced last year, could prove decisive in the U.S. campaign to win over significant portions of the Sunni community, which has formed the bedrock of the insurgency.
The attacks occurred in areas controlled by the Anbar Salvation Council, an alliance of Sunni tribes formed last year to drive al-Qaida from the area. Council officials blamed the attacks on al-Qaida.
"They committed this crime because we have identified their hideouts and we are chasing them," said Sheik Jabbar Naif al-Dulaimi.
In a Web statement Monday, an al-Qaida front organization, the Islamic State of Iraq, warned Sunnis against joining the government security forces.
"We tell every father, mother, wife or brother who does not want to lose a relative to advise them not to approach the apostates and we swear to God that we will use every possible means to strike at the infidels and the renegades," the group said.
