Turkey yesterday extended its crackdown on suspected supporters of a failed military coup, taking the number of members of the armed forces and judiciary rounded up to 6,000. The government said it was in full control of the country.Overnight, supporters of President Tayyip Erdogan rallied in public squares, at Istanbul airport and outside his palace in a show of defiance after the coup attempt, in which at least 290 people were killed.With expectations growing of draconian measures against dissent, European politicians warned Erdogan that the coup attempt did not give him a blank cheque to ignore the rule of law and that he risked isolating himself internationally as he exploited the coup to strengthen his position.Broadcaster NTV cited Justice Minister Bekir Bozdag as saying more arrests were expected.The authorities have rounded up nearly 3000 suspected military plotters, ranging from top commanders to foot soldiers, and a similar number of judges and prosecutors after forces loyal to Erdogan crushed Saturday's coup attempt.One video on Twitter showed detained generals with bruises and bandages. Akin Ozturk, head of the air force until 2015 and identified by three senior officials as one of the suspected masterminds of the coup plot, was among those held.The Foreign Ministry raised the death toll to more than 290, including over 100 rebels, and said 1400 people were hurt."Control across Turkey has been restored and there are no clashes at the moment," a senior official said, adding that groups of coup plotters holding out in Istanbul were no longer a risk."There are still a few important soldiers on the run. I believe they will be captured shortly," the official said.The crackdown appears to intensify a long-standing push by Erdogan to crush the influence of disciples of US-based cleric Fethullah Gulen.Erdogan has accused followers of Gulen, once an ally but now his arch-enemy, of trying to create a "parallel structure" in the courts, police, armed forces and media so as to topple the state.The cleric said he played no role in the attempted coup, denouncing it as an affront to democracy.Erdogan promised a purge of the armed forces even before the coup attempt was over."They will pay a heavy price for this," he said. "This uprising is a gift from God to us because this will be a reason to cleanse our army."At a rally late on Saturday, his supporters demanded that coup leaders be executed. "Let's hang them all!" chanted the crowd in Ankara's central Kizilay Square.Erdogan told them that parliament might consider a proposal to bring back the death penalty, which has been abolished. Erdogan's critics say he will use the purge to create a pliant judiciary, eliminating any dissenting voices in the courts.Some European politicians have expressed disquiet about developments since the coup attempt."[The coup attempt] is not a blank cheque for Mr Erdogan," said French Foreign Minister Jean-Marc Ayrault."There cannot be purges. The rule of law must work," he told the France3 television network.Ayrault said EU ministers would reiterate today when they meet in Brussels that Turkey - which has applied to join the bloc - must conform to Europe's democratic principles.European commissioner Guenther Oettinger said Erdogan would move Turkey away from the core values of the EU and the Nato defence alliance - of which it is a long-standing member - if he used the attempted coup to restrict basic democratic rights."He would strengthen his position domestically but he would isolate himself internationally," Oettinger, told Welt am Sonntag newspaper. ..
