Christian Solidarity Worldwide is calling for “decisive action” after the deadly bombing of a cathedral in Arusha, Tanzania, on Sunday.
The explosion happened during an inaugural Mass at the cathedral, killing three people and injuring more than 60.
The Vatican’s ambassador to Tanzania, Archbishop Francisco Montecillo Padilla, and the Archbishop of Arusha, Josaphat Louis Lebulu, were at the Mass but escaped unharmed.
President Kikwete has described the attack as “an act of terrorism” and vowed to catch the perpetrators.
The bomb was thrown into the cathedral from a motorcycle. Nine people, including three nationals from the United Arab Emirates, one Saudi and five Tanzanians, have been arrested over the bombing.
Mervyn Thomas, chief executive at Christian Solidarity Worldwide, condemned the “senseless” attack.
“Although those arrested have yet to be charged, there is undoubtedly an international element to this attack, which if left unchecked, will severely undermine the stability of the nation,” he said.
