<span style="color: #222222;">The United States has resumed surveillance drone flights over the Black Sea region following a Russian fighter jet intercept on Tuesday that led to the downing of a US surveillance drone, two American officials said yesterday. An RQ-4 Global Hawk flew a mission to the region yesterday, the officials said. Pentagon officials have repeatedly stressed this week the incident would not stop Washington from flying such missions. The downing of a US MQ-9 drone was the first direct US-Russian incident since the Ukraine war began, worsening already tense relations between Washington and Moscow as both countries publicly traded blame.</span><br />
