A Turkish official told Reuters that the "vast majority" of victims were Turkish, but some foreigners were also affected. A law enforcement source told Fox News that FBI assets had not been sent to Istanbul as of Tuesday evening. The Associated Press initially quoted a senior Turkish official as saying that close to 50 people had already died. However, the news agency later backtracked and said the official told them the figure was expected to rise to close to 50. A State Department official told Fox News late Tuesday that they were still trying to determine if any Americans were victims in the attack.
