Plot to assassinate Obama foiled in Turkey

U.S. officials have taken "very seriously" a plot to assassinate President Barack Obama involving a Syrian man who was arrested late last week in Turkey, according to two U.S. officials familiar with the matter.

But the officials strongly cautioned that American presidents are frequent targets of threats that are all watched very carefully, and in this case the alleged plotter did not appear to get anywhere close to Obama during his European tour.

The officials also noted that while Obama gets more threats than usual as the first African-American U.S. president, this particular threat did not force any change to his schedule.

White House officials declined to comment on the matter, citing a policy of not talking about security and threats around the president. U.S. Secret Service officials spoke only briefly about the case.

"We work closely with the host country whenever there is an arrest, which we are doing in this matter," Secret Service spokesman Ed Donovan said.

The plot was first reported by the Saudi Arabian newspaper al-Watan, which revealed that Turkish security services arrested a man of Syrian origins Friday in connection with a plan to kill Obama during his visit to Turkey. Obama was in Strasbourg, France, on Friday for a NATO summit and did not arrive in Turkey for the final leg of his trip until Sunday.

The Saudi paper reported the suspect, who was carrying an Al-Jazeera TV press credential in the name of "M.G.," confessed to authorities after his arrest that he and three alleged accomplices plotted to stab Obama with a knife during the Alliance of Civilizations Summit in Istanbul, which Obama attended on Monday evening. The U.S. officials confirmed those allegations, but stressed to CNN that the information provided by the man is still being verified.
