AKIPRESS.COM - NATO has urged Russia to end airstrikes "on the Syrian opposition and civilians", days after Moscow began raids to support Syria's government, reports BBC.

Moscow says it is targeting Islamic State and other Islamist positions, but U.S.-led allies and Turkey say government opponents are targeted.

Turkish F-16 fighter jets were scrambled after a Russian plane entered Turkey's air space on Saturday.

Russia said the violation was for just a few seconds and due to poor weather.

Saturday's interception took place near Yayladagi in the southern Hatay region, Turkey says. The foreign ministry in Ankara said it had summoned the Russian ambassador to issue a "strong protest".

Turkish jets patrolling the border were also "harassed" by an unidentified plane on Sunday, Turkey said.

A statement by NATO's 28 members, that include Turkey, warned of "the extreme danger of such irresponsible behaviour" and urged Russia "to cease and desist".

U.S. Secretary of State John Kerry said Turkey would have been within its rights to shoot the jets down.
