Obama arrives late for ‘moment of silence’ for Paris attacks

President Obama walked in late Sunday on a moment of silence being held by world leaders in Turkey to honor the victims of Friday’s terrorist attacks in Paris.

Reporters traveling with the president said Mr. Obama had not yet arrived when other world leaders at the G-20 conference in Turkey began their silent observance around a large conference table.

Mr. Obama walked in after they had begun, and took his place next to Turkish President Recep Tayyip Erdogan.
