Officials have said the explosions close to the Syrian border in the Turkish town of Reyhanli, which have killed at least four people and left 18 injured, were caused by two car bombs.
Confirming the casualty figures, Turkey's interior minister Muammer Guler said: "Of course we are worried the numbers could rise".
He said the cars exploded in front of a municipality building and a post office.
