Suicide attackers armed with guns and bombs killed 41 people and wounded scores of others at Istanbul

A family member helps Sacide Bugda, the mother of Abdulhakim Bugda, 24, one of victims, outside the Forensic Medical Center in Istanbul, Wednesday, June 29, 2016. Suicide attackers killed dozens and
wounded more than 140 at Istanbul's busy Ataturk Airport late Tuesday, the latest in a series of bombings to strike Turkey in recent months. Turkish officials said the massacre was most likely the work of the Islamic State group.

Funerals were expected Wednesday for some of the victims — who included at least 23 Turkish citizens and 13 foreign nationals — as Turkish authorities tried to piece together how the attack happened. A Turkish official said authorities are going through surveillance footage and interviewing witnesses to establish a preliminary timeline and details.

The death toll excluded the three bombers, who arrived in a taxi and eventually blew themselves up after coming under fire, according to the government, though there were conflicting reports about exactly where they detonated their explosives.

Earlier, the same official had said none of the attackers got past security checks at the entrance, with two detonating explosives at the international arrivals terminal and the third in the parking lot. The official spoke on condition of anonymity in line with government protocol.

But the HaberTurk newspaper reported that one attacker blew himself up outside the terminal, and two others opened fire near the X-ray machines. The report said an attacker was shot at while running amid fleeing passengers, then blew himself up at the exit. The third attacker went up one level to the international departures terminal, was shot by police and detonated his explosives, according to the report.
