Police officers walked amid the burned-out ruins of a Church of Jesus Christ of Latter-day Saints church in Michigan a day after a former Marine opened fire during a crowded service, killing at least four people and setting the building ablaze. Eight others were wounded and authorities have said they were searching for more victims Monday. A silver pickup truck remained where it had smashed into the brick wall of the church before the gunman got out and started shooting. It happened in Grand Blanc Township, a community outside Flint. The attacker was identified as Thomas Jacob Sanford, who served in the Marines and lived nearby. Authorities say he was later killed by police.

At least 100 federal investigators are responding to an attack in a Michigan community where a former Marine crashed a pickup into a Mormon church, shot into the building and then set it ablaze during a Sunday service. Police fatally shot the man, and at least four people were killed with eight injured. It was the latest of many shooting attacks on houses of worship in the U.S. over the past 20 years, including one in August that killed two children during Mass at the Church of the Annunciation in Minneapolis. Authorities identified the man they said carried out the attack but a motive is not clear yet.

Iran has executed a man accused of spying for Israel, the latest a major wave of executions. Iran identified the man as Bahman Choobiasl. His case wasn’t immediately known in Iranian media reports or to activists monitoring the death penalty in the Islamic Republic. The execution came as Iran vowed to confront its enemies after the United Nations reimposed sanctions on Tehran over its nuclear program this weekend. The European Union followed suit Monday, imposing similar sanctions on Iran.
