President Vladimir Putin said on Thursday that Russia had not received any apology from Turkish leaders over the downing of a warplane, nor any proposals to compensate Moscow.

"We still have not heard any articulate apologies from Turkey's highest political level nor any proposals to compensate for the harm and damage, nor promises to punish criminals responsible for their crimes," Putin said at the Kremlin in televised remarks.

Iraqi Vice President Nuri al-Maliki Thursday accused Turkish President Recep Tayyip Erdogan of pushing the world to the brink of a global conflict after Turkey's downing of a Russian warplane.

Maliki, a former prime minister who remains very influential, lashed out at Erdogan after Turkey shot down a Russian jet it said briefly violated its airspace during operations in northern Syria on Tuesday.

Russian media on Wednesday echoed President Vladimir Putin's tough talk on Turkey's downing of its fighter jet but warned against letting tensions spiral into further conflict.

Front pages were dominated by pictures of the burning Russian jet and Putin's words that its downing was a "stab in the back."

Turkey's Prime Minister Ahmet Davutoglu on Tuesday unveiled a new cabinet stacked with loyal allies of President Recep Tayyip Erdogan, including the strongman's own son-in-law as energy minister.

The announcement came on the same day Turkish fighter jets shot down a Russian war plane on the Syrian border, creating a new security challenge for the government. 

NATO member Turkey on Tuesday shot down a Russian warplane on the Syrian border, an act President Vladimir Putin said would have "serious consequences" for ties between two key protagonists in the Syria war.

The Turkish army said the plane was shot down by two F-16s after violating Turkish airspace 10 times within a five-minute period, an account challenged by Moscow which said it was over Syria.

Long criticized by its allies for taking too soft a line against jihadists, Turkey is taking firmer action against the Islamic State (IS) on the border with Syria after being shaken by attacks on its soil and the Paris assaults.

Ankara is sealing its border to the jihadists who moved to and fro across the frontier during much of the four-year civil war in Syria and stepping up raids against IS suspects.

The charismatic co-chairman of Turkey's main pro-Kurdish party has escaped an assassination attempt, the party said Monday, but the authorities denied any such armed attack had taken place.

Selahattin Demirtas of the Peoples' Democratic Party (HDP) was in his armored vehicle in the mainly Kurdish southeastern city of Diyarbakir late Sunday when it was hit by a single bullet at head height, the party said in a statement.

Sahin Donmez surveys the damage to his house after almost two weeks of street battles between Kurdish militants and the Turkish security forces in the southeastern town of Silvan.

"Look. The fruit of 40 years of work," said Donmez, who fled the town with his family when the fighting began. "Gone up in smoke."

The Royal Canadian Mounted Police says it is investigating a bomb threat that caused a Turkish Airlines flight from New York City to Istanbul to divert and land in Canada.

Halifax Stanfield International Airport said on its Twitter feed early Sunday that Flight 2 had landed safely and that police were at the scene.

The Turkish authorities have seized close to the Syrian border a record haul of almost 11 million pills of the synthetic stimulant drug captagon which is believed to play a crucial part in Syria's civil war, reports said Friday.

Anti-narcotics police confiscated over 10.9 million pills weighing almost two tonnes in two separate raids in the Hatay region on the border with Syria this week, the official Anatolia news agency and Hurriyet daily quoted the interior ministry as saying.
