KABUL, Afghanistan (CNN) -- A 14-year-old who was trained to kill by radicals in the tribal regions of Pakistan now sits in a crowded classroom at a detention facility in Kabul. His only wish is to see his parents again.



Shakirullah, 14, is convicted of planning to carry out a suicide bombing in Afghanistan.



"I miss my parents, my mom and dad," Shakirullah says in soft tones. Like others in tribal regions, he goes by one name.



Shakirullah  is already a convicted terrorist for planning to carry out a suicide bombing. He says Muslim radicals lied and tricked him into becoming a would-be bomber. "I have been detained for trying to commit a suicide attack," he says.



He says his recruiters told him it was his mission as a Muslim to kill British and American soldiers because they were killing Muslims.  Watch teen say recruiters "cheated me" »



They told him that once he blew himself up he wouldn't die because God would save him for being a true Muslim.



Asked what he now thinks of Americans and Westerners, Shakirullah is calm, but quick in his response.



"I don't know. God knows what type of people they are, whether they are good or bad. I don't know them," he says.



Shakirullah now passes his hours in a cell block at a juvenile detention facility in Kabul. He is serving at least five years in detention. He is to be transferred to an adult prison in a couple of years, authorities say.



He hasn't heard from his family in the North-West Frontier Province of Pakistan. He tried to send them a letter through the International Committee of the Red Cross but is not sure it reached them.



"I don't know what they are thinking. They have no news of me," he says.



On this day, Shakirullah attends a rehabilitation class, easily lost in the crowd of boys with shaved heads. All of the children are convicted for various crimes, including theft, fighting and even murder.



Three boys like Shakirullah are here, all guilty of planning to kill themselves and others after being recruited by terrorist groups.



With the increased violence in Afghanistan, international observers say they have seen more and more children being recruited by armed groups and national forces. The Taliban, which ruled Afghanistan with its strict Islamic rule from 1996 to 2001, has regrouped and launched a fierce insurgency.



"As you see in many places in the world, children are being used in armed conflict. They've been recruited as child soldiers; they've been recruited as armed groups. And the phenomena is now impacting, again, Afghanistan," says Catherine Mbengue, the UNICEF representative in Afghanistan.  Watch one boy's struggle begging for food on streets »



Inside the detention center, Shakirullah walks up to his cell, his sandals sliding across the tile floor.



The cell block is empty and has metal bunk beds lined across the wall and a television set, ready for the times they have electricity. Shakirullah shares this space with 10 other boys. He sits in the center of the room with a blanket draped around him.



He barely makes eye contact and looks away as soon as he does. He is shy, but forthright in his words. "I didn't want to do it but he forced me to go," he says of his recruiter.



Rubbing his face with his hand, he says he now spends his time dreaming of his life back home in rural Pakistan. His eyes begin to water and his voice becomes softer when he talks about missing his mother.



Asked what he misses most about her, he says simply, "A mother is a mother."



His was a life of farming and tranquility in Pakistan, he says. It was also a life that took a drastic turn when his father decided to send Shakirullah for studies at a madrassa.



He says his dad wanted him to learn more about Islam and the Quran, something he could not do himself.
