U.S.-back Iraqi forces are gearing up for a new push deeper into Sadr City that could worsen fighting and displace hundreds, a government spokesman in Baghdad said. “There will be a big offensive soon,” said Iraqi government spokesman Tahseen al-Sheikhly. He did not say when the operation would go forward. In east Baghdad the Iraqi government has readied two stadiums and one former military base to serve as camps for Sadr City residents who may be forced to flee the fighting, al-Sheikhly said. “We don’t want any losses in the civilians,” said al-Sheikhly.
