Summary
Three people have been killed and nine injured in an explosion which rocked a Catholic Mass on the Philippine island of Mindanao, officials say
It took place in a gym at Mindanao State University in the city of Marawi, which was the scene of a battle between government forces and Islamic State-linked militants in 2017
The university says it is "deeply saddened and appalled" by the "senseless and horrific" violence, adding it stands in solidarity with its Christian community
Mindanao, the second-largest island in the Philippines, was on Saturday hit by two powerful earthquakes, which prompted initial fears of a tsunami
