German Foreign Ministry spokesman Martin Schaefer said on June 26 that he could "assume with a good conscience that these people who have been incriminated by the US judicial authorities won't set foot on German soil in the foreseeable future, including during the G-20 summit".
The Turkish Embassy sent the Foreign Ministry a list of 50 people who were to accompany Erdogan to Hamburg, local daily Hamburger Abendblatt reported on Sunday.
Schaefer would not confirm or deny an unsourced report in the Welt am Sonntag newspaper that his ministry made clear to Turkey the bodyguards would not be welcome.
"Just like the presence of other foreign military bases or units in other countries of the region, our military presence in Qatar is principally based on a decision taken by the two countries relying on their sovereign rights", ministry spokesman Huseyin Muftuoglu said. "This is what our Turkish partners also know".
"The discussions reportedly centred on the possible surveillance of Turkish intelligence and security risks posed by Turkish nationalists."The Federal Criminal Police Office was not immediately available to comment on the report".
Erdogan's security personnel attack peaceful protesters during demonstration near the Turkish ambassador's residence in Washington DC on May 16, 2017.
Turkey considers the YPG to be an offshoot of the outlawed Kurdistan Workers' Party (PKK) and hence a terrorist group.
USA police brought charges against 12 Turkish security detail over scuffling with protesters outside the Turkish embassy in DC during Erdogan's visit to the U.S. on May 16. In addition to that, yesterday, they detained two of our brothers who intervened ... they issued arrest warrants for 12 of my security officials. "What kind of legal system is this?" "No offense but Turkey is not such an ordinary country [that will ask for permission]", Turkish President said.
Germany's warning to Turkey comes amid significant security concerns around the G20 summit next week.
Separately, some 200 people gathered in Hamburg's southern Harburg district outside a venue that the police has turned into a mass detention center in anticipation of the G20 protests. Eight thousand left-wing extremists are expected to be among them.
Such political uproar at the presence of world leaders including U.S. President Donald Trump and Russian President Vladmir Putin has caused German summit hosts to take extra precautions to avoid violence.
Ankara was infuriated by a US decision last month to arm the YPG, which Washington sees as a vital ally in the battle against Islamic State in its Syrian stronghold of Raqqa but which Turkey deems an extension of the outlawed Kurdish PKK.
