FOXNews.com - Top Stories - Terror Group Warns Spain on U.S. Support: "The government believes the suicide blast killed two of the alleged ringleaders of last month's Madrid train bombings, including one known as 'the Tunisian,' and three other terror suspects.
Two or three suspects may have escaped before the blast, which also killed a special forces officer and wounded 15 other policeman.
The letter gave Spain until Sunday, April 4, to fulfill its demands of ending support for the United States and withdrawing troops from both countries.
'If these demands are not met, we will declare war on you and ... convert your country into an inferno and your blood will flow like rivers,' the letter said.
The group said it had showed its force with the 'blessed attacks of March 11' and the planting of a bomb along the high-speed railway line linking Madrid and the Seville last week, which did not explode.
ABC cited unidentified sources in Spain's National Intelligence Center as saying the letter's authenticity appeared 'fairly credible.' It said the language used in the letter was similar to that used in the video.
The intelligence agency has linked the Ansar group to the Tunisian ringleader killed in the blast Saturday evening.
Ansar al-Islam is an Islamic extremist guerrilla group blamed for terrorist strikes in Iraq, Jordan, Turkey and Morocco.
A respected French private investigator says Spanish police believe that Abu Musab al-Zarqawi (search), a Jordanian terror suspect with links to the Ansar group and Al Qaeda (search), coordinated the Madrid attacks."
