Suspected Kurdish militants in Syria fired rockets across the border into Turkey on Monday, killing at least three people and wounding 10 others, officials said.
The rockets struck a high school and two houses in the town of Karkamis, in Gaziantep province, as well as a truck near a Turkish-Syria border gate, the state-run Anadolu Agency reported.
Interior Minister Suleyman Soylu said the dead include a teacher and a child, who were killed in one neighbourhood. One of the rockets landed on the grounds of a school but there were no fatalities at the school.
A soldier and seven police officers were wounded overnight in separate shelling by suspected Kurdish militants that targeted a border area in Kilis, Soylu said.
Soylu said Turkey would respond to the attacks in the strongest way possible.
The rocket attacks came days after Turkey launched deadly airstrikes over northern regions of Syria and Iraq, targeting Kurdish groups that Ankara holds responsible for a November 13 bomb attack in Istanbul.
The bomb rocked a bustling avenue in the heart of Istanbul on November 13, killing six people and wounding over 80 others.
Turkish authorities blamed the attack on the PKK and its Syrian affiliate the YPG. The Kurdish militant groups have, however, denied involvement.
The Turkish warplanes attacked bases of the outlawed Kurdistan Workers' Party, or PKK, and the Syrian People's Protection Units, or YPG, officials said.
Ankara and Washington both consider the PKK a terror group, but disagree on the status of the YPG. Under the banner of the Syrian Democratic Forces, the YPG has been allied with the US in the fight against the Islamic State group in Syria.
The PKK has fought an armed insurgency in Turkey since 1984. The conflict has killed tens of thousands of people since then.
