Right-wing Dutch lawmaker Geert Wilders calls his anti-Quran film Fitna, an Arabic word that can be translated as discord or chaos. He could be describing the reaction to the film, which he says he has finished but which nobody else has seen.

Protesters have torched Dutch flags in Afghanistan. Pakistan tried to rein in YouTube. And a Cabinet minister postponed his trip to Somalia on Feb. 29 due to "specific threats" linked to the film.

NATO's Dutch secretary general, Jaap de Hoop Scheffer, says he too is worried about the "potentially serious consequences" for alliance troops in Afghanistan, where 1,500 Dutch troops serve in the NATO-led force in the volatile south.

"If they are put in the line of fire because of the film, I am concerned," he said.
