FERGUSON VIOLENCE

Shots fired: Ferguson, Missouri, erupted in violence overnight. Two St. Louis County police officers were shot outside the Ferguson Police Department shortly after midnight.
    Protests became violent in the hours after embattled Ferguson Police Chief Thomas Jackson resigned. He stepped down a week after a Justice Department report slammed his department in the aftermath of the Michael Brown shooting. Jackson's resignation will go into effect March 19. But even though he's about to be out of a job, Jackson will still collect a paycheck. Jackson will receive a severance pay and health insurance for one year, the city said. Jackson's resignation did little to calm tensions. Protests erupted overnight. Shortly after, two officers were shot.

    IRAQ ISIS BATTLES

    Fighting for territory: About three-quarters of the besieged Iraqi city of Tikrit is now back in government control, the head of a key paramilitary force taking part in the attack told CNN. The other 25% is in the hands of about 150 ISIS fighters who continue to hold out. While Iraqi forces piled the pressure on ISIS in Tikrit, the extremist group continued to flex its muscles in Iraq's western Anbar province. ISIS launched a new offensive on the city of Ramadi, west of Baghdad, yesterday morning. Officials believe "this is an ISIS response to the Tikrit operation."

    BIN LADEN IMAGES

    Rare glimpse: We're getting a rare peek at Osama bin Laden's hideout in Afghanistan. The photographs were quietly introduced last month in Manhattan federal court as evidence in the terrorism conspiracy trial of bin Laden lieutenant Khaled al-Fawwaz. The pictures offer a rare look inside Osama bin Laden's lair -- years before al Qaeda flew hijacked planes into buildings or bombed U.S. embassies in Africa and even before the FBI placed bin Laden on its Most Wanted List. The date-stamped photographs from 1996 show a healthy, relaxed, sometimes smiling bin Laden, not yet 40, conversing, hiking, videotaping.

    HELICOPTER SEARCH

Some debris has already been found near Eglin Air Force Base, base spokesman Andy Bourland said. Human remains have also washed ashore. No one is saying what caused the accident, but there's no indication of anything suspicious. Heavy fog has hindered the search.
