Turkish warplanes have bombed parts of north-eastern Syria at the start of an offensive which could lead to conflict with Kurdish-led allies of the US.
Turkey's President Recep Tayyip Erdogan said the operation was to create a "safe zone" cleared of Kurdish militias which will also house Syrian refugees.
According to the Kurdish-led Syrian Democratic Forces (SDF), civilian areas came under attack from Turkish planes.
Turkish ground forces have also been massing on the border.
