Starbucks customers wait in line.
Starbucks' sales in the Middle East were hit after Israel's invasion of Gaza.
  • Starbucks said its sales in the Middle East took a hit after Israel's invasion of Gaza.
  • And events in the region have also impacted US sales, CEO Laxman Narasimhan said.
  • It's the latest sign of consumer boycotts over the war affecting US and European companies.
