Four Catholic Relief Service staff members on their way to a training session in Nairobi, Kenya, were among the passengers aboard an Ethiopian Airlines flight that crashed moments after takeoff in the east African nation.

The accident March 10 claimed the lives of 157 people on board, many of them from humanitarian agencies.

Others on the jetliner included a Georgetown University law school student who was serving as a campus minister and 19 staff members of UN agencies.

Pope Francis offered prayers for the passengers from 35 countries in a telegram on March 11.
