Lakhdar Boumediene writes: On Wednesday, America’s detention camp at Guantánamo Bay will have been open for 10 years. For seven of them, I was held there without explanation or charge. During that time my daughters grew up without me. They were toddlers when I was imprisoned, and were never allowed to visit or speak to me by phone. Most of their letters were returned as “undeliverable,” and the few that I received were so thoroughly and thoughtlessly censored that their messages of love and support were lost.

Some American politicians say that people at Guantánamo are terrorists, but I have never been a terrorist. Had I been brought before a court when I was seized, my children’s lives would not have been torn apart, and my family would not have been thrown into poverty. It was only after the United States Supreme Court ordered the government to defend its actions before a federal judge that I was finally able to clear my name and be with them again.

I left Algeria in 1990 to work abroad. In 1997 my family and I moved to Bosnia and Herzegovina at the request of my employer, the Red Crescent Society of the United Arab Emirates. I served in the Sarajevo office as director of humanitarian aid for children who had lost relatives to violence during the Balkan conflicts. In 1998, I became a Bosnian citizen. We had a good life, but all of that changed after 9/11.

When I arrived at work on the morning of Oct. 19, 2001, an intelligence officer was waiting for me. He asked me to accompany him to answer questions. I did so, voluntarily — but afterward I was told that I could not go home. The United States had demanded that local authorities arrest me and five other men. News reports at the time said the United States believed that I was plotting to blow up its embassy in Sarajevo. I had never — for a second — considered this.

The fact that the United States had made a mistake was clear from the beginning. Bosnia’s highest court investigated the American claim, found that there was no evidence against me and ordered my release. But instead, the moment I was released American agents seized me and the five others. We were tied up like animals and flown to Guantánamo, the American naval base in Cuba. I arrived on Jan. 20, 2002.
