Miami ? A day after the Supreme Court agreed to review the constitutionality of President Bush’s war crimes court, Canadian diplomats sought a promise from the Pentagon Tuesday that it would not seek to execute a teenager being held at Guantanamo Bay, Cuba.

The Pentagon followed the Supreme Court decision Monday with an announcement of its own – five more war-crimes court indictments, notably that of Toronto-born Omar Khadr, who was 15 when he was captured in Afghanistan, and is to be charged with murder as an “unprivileged belligerent.”

Khadr’s detention at Guantanamo has sparked an outcry among some international and human rights lawyers who say that, as a juvenile, Khadr was entitled to special treatment under the Laws of War.

At the same time, Canadian diplomats were working with both the U.S. State and Defense departments to get “the death penalty off the table,” said embassy spokesman Jasmine Panthaky.
