Turkish and Syrian defence and security officials meet for first time in a decade

Move towards peaceful relations represents cause for alarm for more than 4m refugees in Turkey since 2011

Top Turkish and Syrian defence and security officials have held their first public meeting in more than a decade, in a dramatic shift towards normalising relations between the two countries after Ankara backed rebels during Syria's civil war.

The Turkish defence minister, Hulusi Akar, and the head of the country's national intelligence organisation (MIT), Hakan Fidan, met the Syrian defence minister, Ali Mahmoud Abbas, and the notorious spy chief Ali Mamlouk in Moscow, in a meeting attended by the Russian defence minister, Sergei Shoigu.
