BAGHDAD (AP) — Iraq's worst wave of violence in half a decade continues.

Authorities say bombs exploded outside two Sunni mosques in Baghdad late Saturday, killing at least 21 people leaving prayers.

A separate attack at a funeral northeast of the capital killed at least three others.

More than 2,600 people have been killed since the start of April. The violence is raising fears the country is heading back toward the widespread sectarian fighting that peaked in 2006 and 2007.

The pace of the bloodshed has picked up since Ramadan began on Wednesday.
