Reuters reporter Humeyra Pamuk tweets that Turkish military sources are saying that radar shows that rockets fired into Kilis came from IS-controlled areas in Syria.
The Turkish army has fired back.
Reuters is reporting that the person killed when a rocket believed to have come from Syria hit a school in Kilis, Turkey, was a female school employee. A female student was wounded.
More rockets thought to be fired from Syria hit an open field near the school.
Turkish news website The Daily Sabah is citing military sources as saying that it was Katyusha rockets fired from an IS-controlled area of Syria and not mortar shells that hit a school in the town of Kilis near the Syrian border earlier today, killing one person.
Kilis is on the border of a roughly 100 stretch of Syrian border territory controlled by the IS group.
Death Toll Reportedly Increases In Ongoing Clashes With IS In Deir al-Zor
The activist-run Deir al-Zor 24 news website, which publishes news from the Syrian city of Deir al-Zor, is reporting that the death toll of Syrian government forces has increased to 65 killed, amid ongoing clashes. The report cites medical sources in the Deir al-Zor military hospital.
Some 22 IS militants are reported killed, according to Deir al-Zor 24.
IS overran the western Deir al-Zor suburb of al-Bughaliya but Deir al-Zor 24 is denying reports by Syrian state media that the extremist group carried out a "massacre" there.
At Least One Killed In Shelling On Turkish School Near Syrian Border
At least one person has been killed and three others wounded when two mortar shells hit a town in Kilis near Turkey's border with Syria. The shells most likely came from Syria, the mayor of Kilis has said.
AP has interviewed Syrians who recently escaped IS-controlled territory who say that double standards among IS militants are fostering disillusionment.
Syrians who have recently escaped the Islamic State group's rule say public disillusionment is growing as IS has failed to live up to its promises to install a utopian "Islamic" rule of justice, equality and good governance.
Instead, the group has come to resemble the dictatorial rule of Syrian President Bashar Assad that many Syrians had sought to shed, with a reliance on informers who have silenced a fearful populace.
A second British IS militant has reportedly been identified in the latest IS killing video, according to the British media.
Mohammed Reza Haque, 35, a former bodyguard, has been identified as one of five masked men shown in the latest video from the terrorist group, which was released two weeks ago, the Mail on Sunday claimed.
An attack by IS militants on the eastern Syrian city of Deir al-Zor on January 16 has left at least 85 civilians and 50 government troops dead, according to the Syrian Observatory for Human Rights monitoring group and Syrian state media.
State news agency SANA said that IS had carried out a "massacre" in the north-western suburb of al-Balighia, killing "around 300 civilians, most of them women, children and elderly people."
Local media later reported that the IS attack had been repelled.

Istanbul Bomber Reportedly Planned New Year's Eve Attack
The Saudi-born Syrian who killed 10 German tourists in a suicide bombing in Istanbul on January 12 had planned a major attack on New Year's Eve celebrations in the city, according to two senior Turkish officials who spoke to Reuters.
The bomber, Nabil Fadli, had changed his plans after his plot was foiled.
Fadli was born in Saudi Arabia in 1988. He fought alongside IS in Syria and was at one point captured and tortured, possibly by a Syrian Kurdish militia. Fadli entered Turkey last month.
