Turkey's offensive in Syria: Smoke billows in border areas - BBC News
Turkey says its operation is targeting Kurdish militants and creating a "safe zone".
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 says the operation is aimed at creating a "safe zone" cleared of Kurdish militias, which it regards as terrorist groups. Turkey also wants to move Syrian refugees from its territory into the area.
