Unlike Dennis Rodman's basketball diplomacy, a U.N. human rights probe isn't connecting with North Korean leader Kim Jong Un.

Michael Kirby, who heads the U.N. commission examining North Korea's human rights record, says his July 16 letter to the leader hasn't been answered and the government has not cooperated.

Kirby, a former judge in Australia's highest court, told the U.N. Human Rights Council on Tuesday that the commission it created in March nonetheless gathered testimony from dozens of victims and experts at public hearings in Seoul and Tokyo last month that has "given a face and voice to great human suffering."

Following his second trip to visit Kim Jong Un, Rodman announced plans this month to stage two exhibition games in North Korea in January.
