Iraqi forces on Friday entered the center of Fallujah, the Iraqi city longest held by Islamic State, nearly four weeks after the start of a U.S.-backed offensive that cleared out the tens of thousands of residents still there.
Government troops, supported by multiple air strikes from a U.S.-led coalition, recaptured the municipal building, though the ultra-hardline militants still controlled a significant portion of Fallujah, an hour's drive west of Baghdad, and many streets and houses remain mined with explosives.
