The officials say the vehicles blew up in quick succession Wednesday morning in several parts of the city. They say the bombs appeared to target Iraqi security personnel. Kirkuk is an oil-rich region that has long experienced tensions between its Arab, Kurdish and Turkomen communities. Violence in Iraq has declined sharply from the height of sectarian conflict several years ago, but militants still carry out bombings and shootings almost daily. Some information for this report was provided by AP, AFP and Reuters. NEW: Follow our Middle East reports on [1]Twitter and discuss them on our [2]Facebook page.
