Why Did The Us Attack Kenya

Something that challenged my thinking was why would they strike Kenya. The U.S has many other embassy around the world in different countries so what was so important that would make Al- Qaeda risk getting caught by attacking another place. The U.S also has other more powerfull embassy's that Al- Qaeda could of attacked but what made them choose the embassy in Kenya like did have any information that Al-Qaeda wanted that was located at the U.S embassy in Kenya Al-Qaeda knew that the U.S would try to observe and catch them but they still risked it.

Another thing that I was wondering about was about the information leak. Who knew that the U.S was listening to Al-Qaeda's phone conversation was it a select few or a whole group that knew about
