You might have lost an hour over the weekend. I know I lost an hour of sleep. Fortunately, though, we are all right on time for the start of a new week of CNN Student News. Hello, everyone, from the CNN Center in Atlanta, Georgia,I`m Carl Azuz.

First up, officials from NATO, the U.S. and Afghanistan are investigating a shooting that took place in Afghanistan over the weekend. An American soldier allegedly left his base and killed more than a dozen Afghan civilians, including women and children, in two villages. He then went back to the base and turned himself in.

Officials say the alleged shooter was acting on his own. They don`t have any possible motives for the attack. One NATO commander said that the, quote, "appalling incident in no way represents the values of coalition troops or the abiding respect we feel for the Afghan people."

The U.S. ambassador assured the people of Afghanistan that whoever is responsible will be brought to justice.

Tears, prayers and a moment of silence: those were some of the ways in which Japan marked the tragic anniversary of last year`s devastating earthquake and tsunami.

Extraordinary images like these show you how powerful and destructive these natural disasters were. More than 15,000 people were killed by the quake and tsunami.

 And last year, right after it happened, we asked you to share your thoughts and words of encouragement for the victims of these disasters. We asked you to put those on our blog, and here`s what some of you had to say at that time.

From Libby, "The devastation is just so mind- blowing. My prayers go to those affected by this disaster."

Guffey said, "We should show our support for the people of Japan, perhaps by donating money or supplies."

Elizabeth said that, "despite all the chaos, there are people who struggle to live and have hope that things will work out. There is hope in every living witness of this disaster."

And Toyo said, "I`m reading these messages in Japan. Thank you everybody in the world."

 Kyung Lah now has more on yesterday`s anniversary and the memorial ceremonies in one city.

 A year after the tsunami, this is downtown Ishinomaki, still bearing all the scars of when the tsunami roared ashore a year ago. There is so much work and rebuilding to be done.

But for just this moment, this city paused to remember all the victims who had died in the tsunami, people stopping here to lay flowers, to remember the dead. Monks walk through Ishinomaki, chanting for the souls of the dead so that they may rest in peace. But many of the remembrances here in Ishinomaki were on a small scale.

"All I can do is keep going," she says, "and live in the best way I can," one foot in front of the other as a matter of fact Japan continues to recover -- Kyung Lah, CNN, Ishinomaki, Japan.

It`s time to take a look back with a special Women`s History Month edition of this day in history.

 On March 12th, 1912, 18 girls attended the first- ever meeting of the Girl Scouts. Today the organization has more than 3 million members.

In 1993, Janet Reno was sworn in as the first female attorney general in the United States history. She served in that role for eight years.

And in 1994, after considering the issue for decades, the Church of England ordained female priests for the first time.

 The latest report on the employment situation in America came out last Friday. There is a great breakdown of the numbers at our website. We want to walk you through part of them right now.

The big numbers are right at the top. During the month of February, 227,000 jobs were created, and the unemployment rate was 8.3 percent. That`s the same as it was the month before.

It doesn`t include people who are underemployed, but we have that number for you, too. It`s 2.6 million, and those are folks who have either stopped looking for a job or who are working but not as much as they`d want or in the jobs they`d want to work in. Lots of great information here. Check it out at cnnstudentnews.com.

The race for the Republican presidential nomination rolls on, some U.S. territories held events this weekend. Guam, the Virgin Islands and the Northern Mariana Islands. Governor Romney won those.
