Mohyeldin was born in Cairo, Egypt, to an Egyptian father, Medhat Mohyeldin, and a Palestinian mother, Abla Awwad. His father is a certified public accountant in Marietta, Georgia. Mohyeldin has an older brother, Ahmed, who is a resident neurosurgeon at Ohio State University Wexner Medical Center and former professional soccer star for the Atlanta Silverbacks. Mohyeldin lived in Egypt until the age of 5 when his parents emigrated to the U.S.

On July 16, 2014, Mohyeldin witnessed and reported via a series of tweets, the death of 4 Palestinian children who were playing soccer and hide-and-seek on a Gaza beach during the 2014 conflict. The first missile killed one child and the second killed the other 3. The killings were witnessed by many in the international press. Just moments earlier Mohyeldin was kicking a soccer ball with these boys in front of his hotel. The Israeli government claims that the beach was shelled in response to Hamas rocket fire originating from that area.  Although Mohyeldin was a live witness to the event, NBC correspondent Richard Engel reported the story from Tel Aviv. NBC followed by pulling Mohyeldin from Gaza and terminating his reporting duties from Gaza indefinitely. Engel was sent to replace him in Gaza. NBC has been subsequently criticized by independent media outlets for removing Mohyeldin. NBC has not explained its actions and reasons for pulling Mohyeldin.  Mohyeldin was returned to Gaza on July 18, 2014, after NBC received heavy criticism for pulling him out of Gaza. NBC has offered no justification for either pulling him from Gaza, nor sending him back. On Sunday, August 3, 2014, Ayman announced via social media that after 4 weeks on the road he was "taking time to be with family.." Less than 48 hours later, Israel and Hamas agreed to a cease fire.  In the fall of 2014 Ayman moved to New York City to expand his role at NBC/MSNBC. In addition to his role as Foreign Correspondent Mohyeldin also took on the role of fill in anchor across the MSNBC programming family. He also hosts his own show on the MSNBC digital channel Shift called "RoadMap" which covers in depth a wide variety of international and political issues across the globe.
