Kenyan security on high alert ahead of Obama visit
A massive security operation is in place to protect President Barack Obama during his visit to Kenya, which has been frequently targeted by al-Shabab militants based in neighboring Somalia.
Ahead of Obama's arrival Friday evening, large numbers of security forces patrolled in the Kenyan capital, Nairobi. Several US military aircraft were spotted flying around the city. There have also been significant military attacks on Islamic militant targets in Somalia in recent weeks.
