The death toll from the terrorist attack at Istanbul's Ataturk Airport rose to 42 after a young woman died in hospital, a news report said Thursday.
More than 230 people were injured in Wednesday's attack, which Turkish officials and others said was likely carried out by the Islamic State terrorist group, the Anadolu news agency reported.
No group claimed responsibility for the attack in which three assailants stormed the city's main international airport, firing guns and detonating explosives.
The three attackers were also killed during the incident.
Turkish President Recep Tayyip Erdogan vowed to "fight against all terrorist organizations at all costs until the end of terrorism."
"We expect that a resolute stance against terrorist organizations should be adopted by the world and especially Western countries with their parliament, media and non-governmental organizations," he said in a statement.
The country marked a national day of mourning on Wednesday, with flags at domestic and overseas buildings flown at half-mast.
