ATHENS, Greece (AP) — The European Union is promising Greece continued financial support, in the hopes of calming market turmoil triggered by concerns over the government’s survival and the future of its bailout program.

Greek borrowing costs soared Thursday, with the interest rate on the benchmark 10-years bonds jumping to 8.71 percent — a sign investors are more worried about default. And a third day of heavy selling on the Athens Stock Exchange saw shares lose another 2.2 percent in value, after dropping 12 percent in the previous two days.
