CARL AZUZ, CNN ANCHOR: Welcome back to CNN STUDENT NEWS. Thank you for starting off your week with us. International news take center stage first up. Yesterday, followers of the world`s largest religion celebrated Easter Sunday. It`s the most significant day in the Christian calendar. Christians believe Easter is when Jesus Christ rose from the dead having fulfilled the Bible`s prophecies of the Messiah. From Vatican City, headquarters of the Roman Catholic Church, Christianity is largest denomination. Pope Francis called for people to work toward peace, to end world hunger and to help others out of poverty.

Next report today takes us to Yemen. Al Qaeda terrorists recently had a large meeting in the Middle Eastern nation, and suspected drones attacked terrorists over the weekend. The U.S. is believed to have participated, though American officials won`t confirm that. A Yemeni official says at least 12 al Qaeda members were killed on Sunday, ten others on Saturday, though that attack also killed three civilians.

We are also visiting Nepal, home of the world`s tallest mountain. An avalanche rushed down Mount Everest on Friday. It killed 13 people, mostly Sherpas preparing the way for the spring climbing season. Three people are still missing.

JAKE TAPPER, CNN CORRESPONDENT: Everest. The name is synonymous with challenge and all too often, with death.

Friday`s avalanche is the single deadliest incident on Everest in history. Despite the danger, the icy peak that rises more than 29,000 feet into the heavens, still tantalizes adventurers who come for any number of reasons. The guides or Sherpas are often the victims, paving the way, carrying supplies and taking real risks for what are lucrative wages in Nepal.

UNIDENTIFIED MALE: Not only the money that I`m after right now, but even my - from my inner heart, I always wanted to be on the top.

TAPPER: The audacy (ph) has been the subject of countless documentaries.

And feature film such as "Into Thin Air" based on John Krakauer`s bestseller about the 1996 tragedy that left eight climbers dead.

UNIDENTIFIED MALE: I love you.

TAPPER: The dramatic scenes perhaps adding to the galore that has turned the dangerous mountain into a tourist destination. But as the altitude increases, reality sits in.

JOE PRATT, MOUNTAINEER: You can breathe for a while, you are sort of losing ground as you do without oxygen.

TAPPER: In 2012, American Joe Pratt struggled with the lack of oxygen at such a high elevation, though he survived.

UNIDENTIFIED MALE: Anyone who climbed Mount Everest and survives is lucky.

JAKE TAPPER: 344 foreign climbers have been given permission to climb Mount Everest this year, along with an estimated 400 sherpas to guide them home safely. One can only hope that they all come back. Jack Tapper, CNN, Washington.
