ANKARA, Turkey (AP) — Turkey's Foreign Ministry says it has summoned the Russian ambassador after a Russian jet violated Turkey's airspace on Friday, despite several warnings.

A Foreign Ministry statement on Saturday said the plane was warned in Russian and in English before entering Turkey's airspace.

The statement accused Russia of escalating tensions and said Russia would be held responsible for any "dire" consequences.

In November Turkey shot down a Russian plane which violated its airspace near Syria, touching off a crisis between the two countries.
