Turkey retaliates against Syrian shell on its land
The Turkish General Staff on Wednesday said that it had responded to the rocket fire in line with engagement rules.
Hatay Governorate said the explosion left a crater after falling into a dry stream in a field in Reyhanli at 02.35 a.m. (0035 GMT) on Wednesday.
The crater was at 15 meters wide and 7 meters deep, the statement said.
A military command post and homes close to the blast area suffered damage. Witnesses told The Anadolu Agency they fled in panic after they heard the explosion.
Turkey has kept its border with Syria largely open throughout its four-year civil war, but has temporarily closed several border crossings as a security precaution.
Stray rockets and bullets have frequently spilled onto its territory, prompting the Turkish military to return fire in line with its rules of engagement. Bomb attacks which Turkey blamed on fighters loyal to Syrian President Bashar al-Assad killed 50 people in Reyhanlı in 2013.
