The Saudi Arabian man who was put under armed guard at a hospital in the aftermath of Monday's Boston Marathon bombings  is not a suspect, AFP reports.
The Saudi embassy in Washington said on Tuesday that two of its nationals, one man and one woman, were injured in Monday's blasts. Police earlier said that the 20-year-old man was being guarded but was not under detention.
AFP reports that mission spokesperson, Nail Al-Jubeir, said US authorities told the embassy late on Monday “that no Saudi national was a suspect in the Boston Marathon attack and that the Saudi national in question was a witness, not a suspect.”
Monday's explosions left three people dead and left dozens more injured.
The attacks came as Saudi Arabia’s foreign minister, Saud al-Faisal, visited Washington, where he met on Tuesday with Secretary of State John Kerry.
On Tuesday, Saudi's King Abdullah publicly condemned the "heinous terrorist acts," calling the perpetrators "enemies of any humane considerations."
US investigators are still piecing together clues  from Monday’s marathon bombings and are yet to determine whether the assailants were from the United States or overseas.
