Germany warns investors and visitors on Turkey as ties worsen

Berlin

GERMANY'S government warned companies against doing business in Turkey and issued revised guidelines for travellers as Foreign Minister Sigmar Gabriel announced a "re-orientation" of policy towards its Nato ally.

The downgrading of ties threatens to send already stormy relations with President Recep Tayyip Erdogan's government into a downward spiral after both countries traded barbs and threatened economic retaliation following the detention of a German human rights activist earlier this week.
