Czech police arrested Salih Muslim Muhammad, 67, leader of the Syrian Kurdish PYD party, Sunday morning at his hotel in Prague. Local police said they acted on an Interpol warrant issued by the Turkish authorities. DEBKAfile’s sources report that the arrest may sabotage efforts to negotiate a truce in the fighting raging in Afrin since Turkey invaded this Syrian Kurdish enclave last month. Salih Muhammad serves the PYD and its YPG militia’s as liaison officer for their ties with the US, Russia and the Assad regime. The Turks are offering a million -dollar bounty for obtaining his arrest, after placing him on their “Red List” of wanted terrorists. Turkey is submitting an extradition request and a Czech court will decide whether to extradite Muslim or release him.
