Kenya 's Counter-Terrorism Office said Nabhan was related to former senior Al Qaeda in Somalia operative , Saleh Ali Nabhan , who was killed in a U.S. strike in southern Somalia in 2009 . Both men were from Mombasa , Kenya . Saleh Ali Nabhan was killed when U.S. special operations forces used a helicopter to fire on his car in September 2009 . He was believed to be connected to the 1998 bombings of U.S. embassies in Kenya and Tanzania . He was also believed to be behind the coordinated 2002 attack on an Israeli-owned hotel in Mombasa , and a failed attempt to shoot down an Israeli charter flying from Mombasa to Tel Aviv . Throughout the four-day attack at the Westgate mall , it was unclear how many perpetrators were involved . On Day Two , Kenyan authorities said between 10 and 15 attackers were involved . The Islamic militant group Al-Shabaab claimed responsibility . Sources within the group said as many as three attackers were from the United States , two were from Somalia , and the others were one each from Canada , Finland , Kenya and the United Kingdom . Kenya 's Foreign Minister Amina Mohamed told PBS `` NewsHour '' that the attackers came from Kenya , the UK and the U.S. `` The Americans , from the information we have , are young men , about between maybe 18 and 19 . '' They are of Somali origin , but lived in Minnesota or other parts of the United States , she said , adding that underlines `` the global nature of this war that we 're fighting . '' On Day Four , as the operation wound down , Kenya 's President Uhuru Kenyatta said five terrorists were killed by Kenyan forces .
