(FOX NEWS) Kenyan police and security forces continued their attempts early Monday morning to free the last few hostages held in a shopping mall in the capital, Nairobi, by members of an Al Qaeda-linked Somali militant group.

Witnesses reported heavy gunfire coming from the Westgate shopping complex shortly before 6:30 a.m. local time.

Meanwhile, the FBI and the U.S intelligence community are “aggressively” investigating whether or not Americans were among members of an Al Qaeda-linked militant group involved in an attack and hostage situation at a mall in Kenya, a federal law enforcement source told Fox News.
