A church in the Kenyan capital Nairobi has come under grenade attack.
One worshipper died with 10 injured after the God House of Miracle Church was targeted.
The government have blamed previous attacks on Somali-based rebels al Shabaab.
To date Kenyan police say no-one has claimed responsibility for the blast.
It is the latest in a series of attacks in the east African state since it deployed troops into neighbouring Somalia.
The blast happened as the church was crowded with people attending Sunday mass.
Tension is high in Nairobi after the US embassy warned that a terrorist plot against prominent government buildings was expected.
