Tsarnaev, age 19, remains at large for several hours, causing a massive manhunt and lockdown for all of Boston, Cambridge, and many other surrounding communities. The manhunt ends when he is found alive, but seriously injured, hiding in a boat behind a house in Watertown. The two suspects are brothers and had been living together in Cambridge.

July 17, Ukraine: A Malaysia Airlines Boeing 777 crashes in eastern Ukraine near the Russian border, killing all 298 passengers and crew members. The crash occurs in territory where pro-Russian separatists have been battling Ukrainian troops. President Poroshenko says the crash is an act of terror. "I would like to note that we are calling this not an incident, not a catastrophe, but a terrorist act," he says. Ukrainian and American officials say the plane is shot down by a Russian-made surface-to-air missile, citing satellite images. Poroshenko accuses the separatists of launching the missile, which they deny. Russian president Putin also denies having any role in the disaster. A day after the crash, President Obama says he believes that the rebels shot down the plane. He calls the crash a "global tragedy" and faults Putin for continuing to arm the rebels and for not stopping the fighting. Most analysts say rebels may have thought they were targeting a military transport plane rather than a commercial jet. A day before the crash, the U.S. and Europe impose further sanctions on Russia in response to Putin's refusal to stop arming the separatists.

1. On Oct. 29, 2003, New York officials reduced the number of people killed at the World Trade Center in the September 11, 2001, terrorist attacks on the United States by 40 names. The list of casualties dropped to 2,752 from 2,792 for a variety of reasons: some people initially reported missing have been found, there were duplicate names, there was no proof that a person was at the World Trade Center that day, and because of fraud. On January 2004, the number was reduced by 3 more to 2,749.
