1. Iraqi terrorists share grisly photos depicting massacre

Islamic State in Iraq and al-Sham (ISIS) militants posted graphic photos of what looks like hundreds of Iraqi soldiers being killed. Those photos have not been independently verified by NBC News. The militants have taken several cities in Iraq, but an uprising of Shiite men are fighting to defend the capital city of Baghdad. The U.S. will not send troops back, President Barack Obama said Friday, but the aircraft carrier USS George H.W. Bush and two other U.S. Navy ships arrived to the Persian Gulf on Sunday to keep Americans safe. Read more in NEWS.

5. Russia will cut off cash-strapped Ukraine’s gas supply

Talks between Russia and Ukraine on a long-running gas pricing dispute failed Monday, and Russia said they had no responsibility to provide gas to Ukraine since they hadn't paid for it.

For LeBron James and the Heat, four consecutive trips to the Finals are bookended by disappointing runner-up finishes.

7. United States kicks off at World Cup

The United States finally gets its World Cup underway Monday, hoping to reverse its record against Ghana, which has ended the American run at the last two World Cups.

Klinsmann has said repeatedly, “we need to beat Ghana" in the so-called Group of Death.
