First aid workers take an injured man to an ambulance after a rocket hit a road in the Reyhanli district in Hatay province, near the Turkey-Syria border, on January 31, 2018. A 17-year-old girl was killed in a Turkish border town on January 31 by rockets launched from Syria, officials said, as Turkey presses its offensive against a Syrian Kurdish militia. Another individual was also hurt after two rockets hit Reyhanli in Hatay province from northern Syria, the district mayor Huseyin Sanverdi said in a statement, and at least one new rocket hit a street not far a few hours later in the centre of Reyhanli, according to an AFP at the scene. Ankara began a cross-border operation dubbed "Olive Branch" supporting Syrian rebels with air strikes and ground troops in northern Syria against the People's Protection Units (YPG) militia and its western enclave of Afrin on January 20. / AFP PHOTO / OZAN KOSE

Det har vært en kraftig eksplosjon i den tyrkiske hovedstaden Ankara.

En lokal kilde sier til nyhetsbyrået Reuters at ambulanser er sendt til åstedet torsdag kveld.

De første opplysningene tyder på at det dreier seg om en gasseksplosjon ved et skattekontor, ifølge Arab News.

Tyrkia er blitt rammet av en rekke terrorangrep de siste årene. I 2015 ble over hundre mennesker drept i en terroraksjon i Ankara som IS sto bak, ifølge tyrkiske myndigheter.
