Nabro Volcano's 2011 eruption cut Hillary Clinton's June 13th trip short to Ethiopia due to ash which then began disrupting air traffic.
On June 13, US Secretary of State Hillary Clinton had to cut short a trip to Ethiopia due to the ash cloud, which was projected to enter a west-to-east jetstream and enter the atmosphere of countries such as Egypt, Yemen, Israel, Iraq, Jordan, Sudan, Somalia, Djibouti and Saudi Arabia. The ash cloud began disrupting air traffic as UAE-based Emirates flights were cancelled along with Saudi Arabian Airlines flights.
