Yesterday, the East Java Police said they had tracked down seven people suspected of having a connection to the terrorist attacks or the group behind them, two of whom were killed for attacking officers.
A family was also responsible for a series of suicide bombings on churches on Sunday, which claimed 13 lives. Police also reported that Sunday evening, a mother and her teenage daughter were killed in a Surabaya suburb when a bomb being handled by the family's father prematurely went off, CNN reported.
Islamic State has said it was behind the bombings, which were the worst since a series of attacks on churches on Christmas Eve in 2000 killed 15 people and wounded almost 100.More news: President Trump Recalls His Mom In Official Mother's Day Message
One the same day, the family's two teenage sons, 16 and 18, drove their motorcycles to the Santa Maria Catholic Church, where they carried out similar attacks. The father of one of the suicide bombing families was the head of his local branch. "While the father Dita Oepriarto, detonated a auto bomb outside a third church". "We are angry", said an official, but he insisted that civilians cooperate with police proceedings.
ISIS has claimed guilt for the attacks, reports The Jakarta Post. The father, 50-year-old Tri Murtiono, took his wife and three children, strapped them with homemade bombs, and blew themselves up at the entrance gate to the police station.
The Pontiff said: "I am particularly close to the dear people of Indonesia, especially to the communities of Christians of the city of Surabaya, which were hit hard by the serious attack on places of worship".
In Jakarta, Indonesia's capital, the Indonesian Church Association added its condemnation.
Indonesia, which is set to host the Asian Games in just three months, has long struggled with Islamist militancy, including the 2002 Bali bombings that killed more than 200 people - mostly foreign tourists - in the country's worst terror attack. Indonesia is the world's most populous Muslim country with more than 82 per cent of its roughly 260,500,000 people following Islam.
