Runner Meb Keflezighi became the first American male athlete to win the Boston Marathon in three decades as onlookers chanted "USA! USA!."
It was an emotional performance in a city still recovering from last year's fatal bombing attack on the world-renowned race.
Keflezighi, who was born in Eritrea but is now a U.S. citizen, pulled ahead of a pack of elite African runners a little more than halfway into the race and held off a late challenge by Kenya's Wilson Chebet, finishing in two hours, eight minutes and 37 seconds.
