Good morning. Here are some of the stories we’re following today:

1. Day of mourning for victims of Paris attack

The funerals of four people killed in Friday’s attack on a kosher market in Paris were held in Jerusalem on Tuesday as mourners also gathered in France. The ceremony was attended by Israeli Prime Minister Benjamin Netanyahu, who told families that their relatives were “killed only because they were Jewish." French President Francois Hollande also led a ceremony honoring the three police officers killed during last week’s terror attacks, which began at the offices of the satirical French magazine Charlie Hebdo. Meanwhile, the editors of Charlie Hebdo plan to roll out an unprecedented 3 million copies Wednesday of its first issue since the attack. The cover will feature a cartoon of the Islamic Prophet Muhammad in tears. Read more in NEWS.

2. White House: Senior official should have gone to Paris

Obama administration spokesman Josh Earnest conceded Monday that the White House should have sent a high-ranking official to attend Sunday’s solidarity march in Paris that drew 3.5 million people. The only noted American official in attendance was the U.S ambassador to France.

But Earnest said going to Paris to a last-minute outdoor event posed “significant security challenges.” Read more in POLITICS.

3. Second black box retrieved from AirAsia crash

Divers in the Java Sea found the second black box of Flight 8501 on Tuesday — a key tool in helping to determine why the jetliner crashed after leaving Indonesia last month. Searchers have also been trying to locate the main section of the aircraft's cabin, where many of the victims are believed to be entombed. Decomposition is making identification more difficult for desperate families waiting to bury their loved ones. Only 48 bodies of the 162 people on board have been retrieved. Read more in NEWS.

The revelry in Columbus, however, turned violent and police in riot gear used tear gas to disperse the crowds. Read more in SPORTS.

5. CENTCOM’s Twitter back up after hacking

U.S. Central Command’s Twitter and YouTube accounts were up and running Tuesday, a day after pro-ISIS messages posted by unknown hackers forced the military to temporarily take them down. Hackers who gained control of the Twitter account replaced CENTCOM's banner and profile avatars with images from the "CyberCaliphate," one of which read "i love you isis." The hackers posted tweets in which they claimed to have broken into U.S. military computers and extracted information about service members and their families. Twitter said that it does not comment on individual accounts, but that the company was helping the Pentagon resolve an "account security issue." Read more in NEWS.

The University of Virginia had suspended all of its fraternities and sororities in the wake of the scandal, and officials had come up with new guidelines on how to deal with sexual assaults. But discrepancies were found in the Rolling Stone piece, leading the university to reevaluate its position on Greek activities. Read more in NEWS.
