Kenya on high alert after al-Shabab attack

Security has been stepped up across Kenya since al-Shabab gunmen attacked a Nairobi hotel complex this month, killing 21 people.

The crackdown is disrupting life – military and police checkpoints dot the road and due to the frequent stops and searches, a four-hour journey now takes a gruelling 10 hours.
