25 + 20 + 5 + 4 + 3 = 57

Some basic Iraqi arithmetic: 25 + 20 + 5 + 4 + 3 = 57

BAGHDAD (Reuters) - A car bomb killed 25 people on Thursday at a busy intersection in Baghdad where minibuses pick up and drop off passengers, while 20 beheaded bodies were found on a river bank south of the capital, Iraqi police said.

Another car bomb in Baghdad targeting motorists queuing for petrol killed five people, police said. Mortar bombs also killed four people in two separate neighborhoods in the city.

In the southern city of Basra, a roadside bomb killed three British soldiers and wounded another, the British military said.

The latest attacks underscore the strength of militants in Iraq despite the arrival of 28,000 additional U.S. troops. The unrelenting violence is pushing Iraq to the brink of all-out civil war between majority Shi'ites and minority Sunni Arabs.
