WASHINGTON - A State Department report on terrorism due out next week will show a nearly 30 percent increase in terrorist attacks worldwide in 2006 to more than 14,000, almost all of the boost due to growing violence in Iraq and Afghanistan, U.S. officials said Friday.

The annual report's release comes amid a bitter feud between the White House and Congress over funding for U.S. troops in Iraq and a deadline favored by Democrats to begin a U.S. troop withdrawal.

Secretary of State Condoleezza Rice and her top aides earlier this week had considered postponing or downplaying the release of this year's edition of the terrorism report, officials in several agencies and on Capitol Hill said.

In 2004, the State Department was forced to correct a first version of the report that the administration had used to tout progress in Bush's war on terror. The original version had undercounted the number of people killed in terrorist attacks in 2003, putting it at less than half of the actual number.

In 2005, the department was again accused of playing politics with the report when it decided not to publish the document after U.S. officials concluded that there were more terrorist attacks in 2004 than in any year since 1985.

The outcry forced Rice to drop that plan and publish the report.
