IRBIL, Iraq (AP) - The Obama Administration and the Vatican condemned the Islamic State group Wednesday for razing Iraq's oldest Christian monastery, a 1400-year-old structure that survived assaults by nature and man for centuries before it was deliberately destroyed by extremists.

At the United Nations, UNESCO Director General Irina Bokova said reducing St. Elijah's monastery in Mosul to a field of rubble was malicious and misguided. The Associated Press confirmed the news with exclusive satellite images published early Wednesday.

"Despite their relentless crimes, extremists will never be able to erase history," said Bokova, who called the demolition a war crime. "It also reminds us how terrified by history the extremists are, because understanding the past undermines the pretexts they use to justify these crimes and exposes them as expressions of pure hatred and ignorance."

"A big part of tangible history has been destroyed," said Rev. Manuel Yousif Boji. A Chaldean Catholic pastor in Southfield, Michigan, he remembers attending Mass at St. Elijah's almost 60 years ago while a seminarian in Mosul.

"These persecutions have happened to our church more than once, but we believe in the power of truth, the power of God," said Boji. He is part of the Detroit area's Chaldean community, which became the largest outside Iraq after the sectarian bloodshed that followed the U.S. invasion in 2003. Iraq's Christian population has dropped from 1.3 million then to 300,000 now, church authorities say.

At the Vatican, spokesman Rev. Federico Lombardi noted that since the monastery dates back to the time Christians were united, the place would be a special one for many. He said it was the first news he had had of the destruction.

The monastery, called Dair Mar Elia, is named for the Assyrian Christian monk - St. Elijah - who built it between 582 and 590 A.C. It was a holy site for Iraqi Christians for centuries, part of the Mideast's Chaldean Catholic community.

In 1743, tragedy struck when as many as 150 monks who refused to convert to Islam were massacred under orders of a Persian general, and the monastery was damaged. For the next two centuries it remained a place of pilgrimage, even after it was incorporated into an Iraqi military training base and later a U.S. base.

Then in 2003 St. Elijah's shuddered again - this time a wall was smashed by a tank turret blown off in battle. Iraqi troops had already moved in, dumping garbage in the ancient cistern. The U.S. Army's 101st Airborne Division took control, with troops painting over ancient murals and scrawling their division's "Screaming Eagle," along with "Chad wuz here" and "I love Debbie," on the walls.

A U.S. military chaplain, recognizing St. Elijah's significance, kicked the troops out and the Army's subsequent preservation initiative became a pet project for a series of chaplains who toured thousands of soldiers through the ruin.
