US Investigate on American Killed in Kobane

U.S. government agencies are investigating on an American fighting with the ISIS militant group killed recently in the besieged Syrian border town of Kobani.
U.S. officials said law enforcement and intelligence agencies were trying to confirm Internet postings by ISIS militants which last weekend reported the "martyrdom" of a fighter known as Abu Muhammad al-Amriki.
The nom-de-guerre indicated that the man considered himself an American. In a video posted on YouTube in February, a bearded man believed by U.S. authorities to be the same individual is seen speaking English with a heavy foreign accent.
The man in the video said he had lived in the United States for about 10 years before traveling to Syria to join ISIS militants.
U.S. officials say at least a handful of Americans -including a Michigan woman and men from Florida and Minnesota - have died in Syrian fighting over the last two years.
One of the men, Moner Mohammed Abusalha, blew himself up in a suicide bombing earlier this year, they say.U.S. and European authorities are deeply concerned about Western foreign fighters in Syria who might return to their home countries to carry out attacks.
On Tuesday, presidential counter-terrorism advisor Lisa Monaco discussed this threat with New York Mayor Bill De Blasio and Police Commissioner William Bratton, according to a White House announcement.
