Spanish Prime Minister Jose Luis Rodriguez Zapatero is scheduled to testify Monday before a legislative investigative committee to give his version of events surrounding the Madrid train bombings nine months ago on March 12.

Mr. Zapatero will address allegations that his Socialist Party helped instigate protest rallies on election eve, three days after the terrorist attacks killed 191 people.

Angry demonstrators accused the pro-U.S. government of Prime Minister Jose Maria Aznar of making Spain a target for al-Qaida. The Socialists went on to win the election, even though the ruling Popular Party had been leading in all public-opinion polls.

During his testimony, Mr. Zapatero is also expected to invite all political parties to join forces in fighting international terrorism.
