Former President Barack Obama has arrived in Kenya, his father’s home country, in what was expected to be a lower-profile visit than the ones he made to the country as senator and president.

Mr. Obama traveled to Kenya on Sunday to promote the opening of a sports and training center that his half sister, Auma Obama, founded through her charitable foundation, The Associated Press reported.

In a Twitter post on Sunday night, President Uhuru Kenyatta of Kenya showed photos of himself meeting a tieless Mr. Obama in Nairobi, the capital. “It was a great pleasure to welcome you back,” he wrote in welcoming Mr. Obama.

In another Twitter post, sent from the official presidential account, Mr. Kenyatta said he and his deputy had “had a refreshing chat” with the former American president and his half sister.
