A series of attacks including a blast near an Internet cafe in a Sunni area of Baghdad killed nine people and wounded dozens on Sunday in and around the Iraqi capital. The attacks came amid heightened sectarian tension following a deadly security crackdown on a camp in northern Iraq run by Sunnis, protesting what they consider to be their second-class treatment by the Shiite-led government. Government investigators say the April 23 incident left 40 people dead, while a spate of follow-up attacks and battles has killed well over 200 more.
