The Pentagon on Wednesday said an eruption of violence in southern Iraq, where US-backed government forces were battling Shiite militias, was a "by-product of the success of the surge."

Pentagon press secretary Geoff Morrell said it showed that the Iraqi government and security forces were now confident enough to take the initiative against Shiite extremists in the southern port of Basra.

"Citizens down there have been living in a city of chaos and corruption for some time and they and the prime minister clearly have had enough of it," he said at a Pentagon press conference.

At least 20 people were reported to have been killed in two days of fighting in Basra and another 20 in clashes in the Sadr City district of Baghdad, a bastion of Shiite militias that follow radical cleric Moqtada al-Sadr.
