Syria denies role in Turkey blasts
Syria has denied being responsible for two car bombs which killed 46 people in a Turkish border town.
Turkey's foreign minister has blamed the world's inaction on the Syrian conflict for the "barbarian act of terrorism" that claimed dozens of lives near the border.
Ahmet Davutoglu's comments in Berlin came a day after a twin bombing in the small town of Reyhanli, in the southern Turkish province of Hatay bordering Syria, that left at least 46 people dead and 100 others wounded.
They also followed a vigorous denial by Syria of any links to Saturday's blasts - the deadliest incident on Turkish soil since the Syrian conflict began.
Syrian Information Minister Omran al-Zoubi told a news conference on Sunday his country "did not commit and would never commit such an act because our values would not allow that".
Turkish police say that nine people have been arrested in connection with Saturday's attacks in Reyhanli.
Ankara has said that it suspects the involvement of Syrian intelligence.
Turkish Prime Minister Recep Tayyip Erdogan said Turkey would not be dragged into a "bloody quagmire".
He called on Turks to be "extremely careful, extremely vigilant... in the face of provocations".
"We will not be trapped. The aim of these attacks is to pit Turks against each other and create chaos. So I call on all my citizens to keep calm."
The Turkish government said on Sunday that the number of people killed in the blasts had risen to 46 and that more than 50 others were still being treated in hospital.
All nine of those arrested in connection with the attacks were Turkish citizens, officials said.Turkey, a Nato member, is a strong supporter of the opposition in Syria's civil war and a vocal critic of President Bashar al-Assad's government.
The US and Nato have condemned the bombings and expressed support for Turkey.
Hundreds of mourners have been attending the funerals of the victims in Reyhanli, which is home to many Syrian refugees.
Zoubi said that "it is not anyone's right to hurl unfounded accusations".
"We were saddened by the martyrs' deaths" [on] Saturday in the town of Reyhanli," he said.
"It is [Turkish Prime Minister Recep Tayyip] Erdogan who should be asked about this act. He and his party bear direct responsibility."
Zoubi also launched what correspondents say was one of the harshest personal attacks on Turkey's prime minister by an Syrian official so far. He demanded that Erdogan "step down as a killer and as a butcher".
He added it was the Turkish government that had facilitated the flow of arms, explosives, vehicles, fighters and money across the border into Syria.
Zoubi said that this had turned the border areas into centres for international terrorism and the Turkish leadership had to take political and moral responsibility for it.
Turkish Foreign Minister Ahmet Davutoglu has vowed to catch those behind the attack. On Sunday he said that he believed fighters loyal to Syrian President Assad were responsible.
The Syrian opposition coalition has added its voice to the Turkish accusations that Damascus was behind the bombings, saying it was a blatant attempt to drive a wedge between Turkey and the thousands of Syrian refugees who have been given shelter on the Turkish side of the border.
