Fifty people suspected of involvement in Iraq's insurgency have been detained in Najaf following Sunday's suicide car bombing in which the death toll has risen to 52 killed and over 140 wounded, the governor said. Provincial governor Adnan al-Zurfi gave few details at a news conference but said at least one suspect held a foreign Arab passport. Many of the wounded, he said, were making a good recovery after the attack, which followed a similar blast in nearby Kerbala that killed at least 14 people and wounded about 40. The total toll on the day was at least 66 dead and over 180 wounded.
