ANKARA -- Turkey's state-run news agency says authorities have captured two more people suspected of being part of a group of soldiers who raided President Recep Tayyip Erdogan's seaside hotel during the failed coup.
Anadolu Agency says the two were captured early Monday near the Aegean resort of Marmaris, bringing the number of suspects caught in the operation that began late Sunday to 11. One suspect is still on the run.
Erdogan had been on vacation during the July 15 coup. The soldiers raided his hotel in an attempt to capture or kill the president but are believed to have missed him by an hour or less.
Meanwhile on Monday, an official said Turkey's Foreign Ministry had summoned a German diplomat in protest at a court decision that prevented Erdogan from addressing a demonstration in Germany. In Cologne on Sunday, thousands rallied to denounce the failed July 15 coup in Turkey and show support for Erdogan. The Turkish president had intended to address the demonstration, but a regional court ruled that no messages from speakers elsewhere - such as politicians in Turkey - could be shown on a video screen at the rally.
The Turkish government accuses U.S.-based cleric Fethullah Gulen of being behind the coup, which saw more than 200 people killed. Gulen denies any knowledge of the attempt to overthrow the government.
A Turkish-language draft document obtained by CBS News shows one motivation that may have driven the failed coup plotters, according to a senior Turkish government official.
According to a source, the document shows that a prosecutor intended to launch a court case against Erdogan and other top officials on charges of colluding with terrorists, citing as evidence their six-year attempt to negotiate a peace settlement with PKK Kurdish rebels.
Gulen's supporters serve in large numbers in the police, judiciary, and business community in Turkey, and have used lawsuits and court cases in the past against their foes, including their former allies in the AKP (Erdogan's party). The Gulenists are staunchly against Kurdish autonomy and have been at odds with the PKK for influence in the southeast of the country; they attempted to indict the head of Turkey's intelligence agency in 2012 on terrorism charges because of his role in negotiating with the PKK.
The source told CBS News that the draft indictment was found in the office of prosecutor Mehmet Sel, one of thousands of government officials dismissed from their posts in recent weeks. He was arrested on charges of participating in the coup.
