BAGHDAD - At least six Iraqi border guards were killed on Saturday when a suicide bomber drove a truck packed with explosives into an outpost near the border with Saudi Arabia in an attack claimed by Islamic State.
In a statement posted online, Islamic State said the attack on an outpost in the desert area of Iraq to the west of Nukhaib targeted the army and "rejectionist" militias -- a term used by the Sunni militants to describe Shi'ite Muslims.
Interior Ministry spokesman Saad Maan said in a statement six guards had been killed, including their commander, and 10 others wounded.
Border police sources put the death toll among higher at eight.
Iraqi government forces, backed by US-led air strikes, have been trying to push back Islamic State militants since they swept through mainly Sunni Muslim provinces of western and northern Iraq last year.
