The state-run Anatolian news agency said the children had been taken to nearby hospitals.
Southeast Turkey is the scene of a conflict between state security forces and the separatist Kurdistan Workers Party (PKK).
Improvised explosive devices are commonly used by the PKK against the armed forces.
A large number of mines have also been laid by the armed forces in the region.
More than 40,000 people have been killed in the fighting since the PKK took up arms against the state in 1984.
