Julian Assange is wanted for crimes that put at risk the lives of people in Iraq, Iran and Afghanistan who had helped the West, some of whom later disappeared, said a lawyer acting for the United States in its bid to extradite him.

Almost a decade since his WikiLeaks website enraged Washington by leaking hundreds of thousands of secret U.S. documents, Assange, 48, is fighting extradition from Britain to the United States where he is accused of espionage and hacking.

He was wanted, said James Lewis, lawyer for the U.S. authorities, not because he embarrassed the authorities but because he put informants, dissidents, and rights activists at risk of torture, abuse or death.
