Example Input: Washington (CNN) -- President Barack Obama used a Memorial Day ceremony to say it is time for America to properly welcome home Vietnam veterans and show them and their families the respect and gratitude they deserved but didn't receive decades ago. "You came home and sometimes were denigrated when you should have been celebrated," Obama said beneath a scorching sun at the Vietnam Veterans Memorial. "It was a national shame, a disgrace that should have never happened. That's why here today, we resolve that it will not happen again." The event, which launched a 13-year Vietnam War 50th anniversary commemoration, was the culmination of a day of somber events on the annual holiday honoring America's war dead.NEW: President Obama calls the denigration of Vietnam veterans a "national shame""America will be there for you," Obama tells veterans and their familiesMemorial Day launches a 13-year commemoration of the Vietnam War's 50th anniversaryObama lays a wreath to the fallen at Arlington National Cemetery

Example Input: Lagos, Nigeria (CNN) Facebook founder Mark Zuckerberg's visit to Nigeria, his first to sub-Saharan Africa, has put the country's tech businesses firmly in the world's spotlight. Zuckerberg staged a surprise visit to the country's economic capital Lagos on Tuesday and his first stop was a local innovation center and tech hub in Yaba, an area on the mainland of Lagos known as Nigeria's Silicon Valley. There was no fanfare amid tight security and some of those working at the Co-Creation Hub, called CcHUB, didn't even know Zuckberg was coming. He appeared nervous, a little startled even, as he launched into an impromptu speech about why he was there.Zuckerberg causes a stir with surprise visit to Nigeria on TuesdayEntrepreneurs say it will give country's startup industry a boost

Example Input: (CNN) -- During the last four months, the people of Ukraine have been fighting for their freedom, independence and European path in a war started by Russia-backed terrorists and their accomplices.

We've seen reports of the pro-Russian thugs shooting women and children, cynically calling it a "protection of the Russian-speaking population." The price we are paying to bring peace back to the regions of Donetsk and Luhansk in eastern Ukraine is too high. Ukrainian President Petro Poroshenko has proposed the decentralization of power as part of his peace plan. It means more freedom, more economic autonomy and more opportunities to use languages spoken in a particular community for every region.Pavlo Klimkin: With downing of MH17, price of peace in eastern Ukraine already too highKlimkin: Ukrainians know bitterness of loss, share grief with families of the deceasedHe says the guilty must be promptly punished
