Indonesian officials said Monday that a recently married couple with suspected militant links used pressure cooker bombs to blow themselves up outside the Roman Catholic cathedral. The attack wounded 20 people, including four church guards, and broke windows at the church and nearby buildings in Makassar, the capital of South Sulawesi province.

A Security Council press statement late on Tuesday denounced the attack as a "reprehensible" act of terrorism and reiterated that "any acts of terrorism are criminal and unjustifiable, regardless of their motivation".
