(NBC NEWS) Israeli Prime Minister Benjamin Netanyahu called Turkish premier Tayyip Erdogan on Friday to apologize for a raid by Israeli marines that killed nine Turkish activists.

President Barack Obama took part in the half-hour call, which was made from a trailer on the tarmac at Tel Aviv’s Ben Gurion Airport before Obama left Israel for Jordan.

Relations between Israel and Turkey, once strong, soured after deaths of the activists, who were on a boat attempting to go through Israel’s naval blockade of the Gaza Strip in 2010 when it was boarded by the marines.
