Rockets fired from Syria for the second time this week left eight people injured Tuesday in Turkey's southern Kilis province, according to a statement from the governor's office.
Two of those injured were in serious condition as a result of the two rockets, the statement said.
The attacks come a day after several rockets hit the area, leaving 12 injured.
Turkey's military shelled Islamic State positions Monday night and early Tuesday in northern Syria in response to the rocket fire, the state-run news agency Anadolu reported.
Fighting is ongoing across the Turkish-Syrian border between Syrian rebels, including factions said to be backed by Turkey, and Islamic State fighters.
The rebels, including Islamist groups, are seeking to take ground from Islamic State, but the extremists this week managed to reverse the opposition fighters' recent gains along the border.
