The House on Tuesday overwhelmingly reaffirmed that the U.S. government should recognize the century-old killings of 1.5 million Armenians as a genocide.

The resolution, which is not legally binding, marked the first time in 35 years that either chamber of Congress labeled as genocide the mass killings of Armenians at the hands of the Ottoman Empire, which is now modern-day Turkey, between 1915 and 1923 . A similar House resolution passed in 1984.
