On Tuesday, al-Nusrah Front sharia official Abu Sulayman al-Muhajir posted on Twitter photos of the purported American suicide bomber and identified him as "Abu Hurayra Al-Amriki." The American, he wrote "Performed a martyrdom operation in Idlib, Jabal Al-Arba'een," adding "May Allah accept him."

U.S. officials have not yet confirmed whether Al-Nusrah Front's assertion is true. There are no other known cases of Americans undertaking suicide attacks in Syria.
A video allegedly of the May 25 suicide attack was posted to YouTube. In the five minute video, the alias of the driver is reported as "Abu Hurayra al-Muhajir" -- aka "the Emigrant."
