US Secretary of State Antony Blinken paid a visit to Haiti on Thursday to evaluate progress in wresting control from gangs that have taken over some 80 percent of the capital Port-au-Prince and push for long-awaited elections. Blinken, the highest-ranking US official to travel to the battered country in nearly a decade, arrived two months after Kenya sent police officers to launch a long-awaited international force aimed at restoring order.
