It's Tuesday and here are the 5 things to know for your New Day

NETANYAHU SPEECH

What will he say?: At times, Israeli leader Benjamin Netanyahu and U.S. President Barack Obama barely seem to tolerate each other. Today's speech by the Israeli Prime Minister probably won't help matters. Netanyahu is expected to spill secret details of the Iran nuclear talks when he addresses Congress. An agreement between Tehran and six world powers is in its delicate final stage. House Speaker John Boehner blindsided the White House by inviting the Israeli leader without advance notice.

    LOS ANGELES SHOOTING

    Video evidence: Lots of questions surround the shooting of a man by L.A. cops over the weekend. Police say the man reached for an officer's gun, which prompted other officers to open fire. There was a struggle before the shooting and at least one officer tried to use a stun gun on the man. Two of the officers were wearing and had activated their body cameras, the police chief said. Police say they'll review the video. The district attorney's office is investigating too. The shooting is the latest high-profile incident involving lethal force by police, in the wake of officer-involved killings in Ferguson, Missouri, and New York last year.

    BOKO HARAM

    Graphic videos: Islamist extremist group Boko Haram joins ISIS in posting the apparent beheadings of its enemies online. The six-minute video shows two men with their arms tied to their backs. Later, the video switches scenes that show what appear to be the bloody severed heads of the two men placed on their bodies. Boko Haram said the men were suspected spies. The group has released beheading videos before, but never online.

    ISIS TWITTER

    Targeting Twitter: ISIS supporters have threatened Twitter founder Jack Dorsey and other Twitter employees for shutting down accounts that promote ISIS. An online illustration shows Dorsey in crosshairs, followed by multiple death threats. Twitter's terms of service forbid hate speech, threats and posts that promote terrorism. Twitter said it is working to confirm whether the threats are serious.

    ISIS TIKRIT

    Fighting back: Iraqi forces have launched an offensive to retake the city of Tikrit from ISIS. Sunni and Shiite militiamen are joining the Iraqi army in the effort, state-run TV reported. ISIS took Tikrit in June, shortly after capturing Iraq's second-largest city, Mosul. The offensive involves around 30,000 fighters. This is the biggest test for an army trying to claw back territory that fell to ISIS last summer after a string of dramatic defeats.
