Attacks in Iraq killed eight people and wounded 33 on Wednesday, security officials said, as Baghdad hosted key nuclear talks in its latest effort to emerge from decades of isolation. Three people were killed and 14 wounded in a shooting and three roadside bombings in Baquba, capital of Diyala province north of the capital, a police lieutenant colonel and Dr Ahmed Ibrahim of Baquba General Hospital said. And a roadside bomb exploded near a bus carrying Lebanese Shiite pilgrims near Ramadi, capital of Anbar, a Sunni Arab province west of Baghdad, killing three and wounding 10 others, police and medical sources said. Iraq is home to some of the holiest sites in Shiite Islam, to which hundreds of thousands of pilgrims flock each year. Pilgrims have come under repeated attack by Sunni insurgents, often with bombs. Two policemen were killed and five wounded in attacks in the northern oil hub of Kirkuk, capital of a province that Kurdish leaders want to incorporate into their autonomous region in northern Iraq, against Baghdad’s wishes. Unknown gunmen attacked the house of a high-ranking police officer, killing a police guard, another high-ranking officer in the Kirkuk police said.
