BRITAIN-TERROR

LONDON — The new head of Britain's electronic eavesdropping agency says U.S.-based social media have become "command-and-control networks" for terrorists and criminals, and tech companies are in denial about their misuse. Writing in Tuesday's Financial Times, GCHQ chief Robert Hannigan said British intelligence agencies know that IS extremists use messaging services like Facebook, Twitter and WhatsApp to reach their peers with ease. He said spy agencies need to have greater support from the U.S. technology companies which dominate the Web in order to fight militants and those who host material about violent extremism and child exploitation.

BRITAIN-PORT TO JIHAD

PORTSMOUTH, England — Royal Navy sailors used to swagger out of this great seaport at the zenith of the British Empire, manning the warships and trading vessels that made this nation rich and powerful. Today a handful of young men are again leaving to go to war — but this time they have sworn allegiance to foreign terrorists. It is a sign of the times that Portsmouth, with its tradition of naval glory, finds itself trying to persuade young British Muslims not to follow six locals who traveled to Syria to join forces with Islamic State extremists battling President Bashar Assad.

GERMANY-BERLIN WALL-TWIN TOWNS

BOECKWITZ, Germany — Friedrich-Wilhelm Lenz was only a toddler when the wall went up that split his family's 75-hectare farm in two — dividing the cow stall and even a restaurant on the land. It was 1952, and East German authorities were erecting the wooden barrier that broke up the twin towns of Zicherie in the capitalist West and Boeckwitz in the communist East. The two had operated as one for centuries — sharing markets, schools and social clubs — and had long been the site of the Lenz family farm. By Kerstin Sopke. SENT: 600 words, photos.

FRANKFURT, Germany — Germany's luxury automaker BMW AG saw net profit slip 1.2 percent in the third quarter due to non-cash losses on foreign currency hedges and the reduced value of a stake in a key supplier.

High Commissioner for Refugees Antonio Guterres told The Associated Press on Tuesday that the goal is achievable despite the chaos and conflict in parts of the world that has left an estimated 10 million people without proper legal documentation.
