The FBI, along with local authorities, is investigating explosions at two different churches in Las Cruces, New Mexico, which took place about 30 minutes apart from one another. There were no injuries in the incidents, with witnesses saying both churches were evacuated, ABC News reported.

Police spokesman Dan Trujillo told the Las Cruces Sun News that the first explosion occurred near Calvary Baptist Church at about 8 a.m., while the next happened at Holy Cross Catholic Church about half an hour later. The explosions caused just minor damage. The explosion at Calvary Baptist reportedly went off in a mailbox near the church, while the explosion at Holy Cross took place in a nearby trashcan during morning mass.

Monsignor John Anderson was passing communion in Holy Cross Catholic Church when a loud bang interrupted services. "I was right in the middle of saying the words 'take and eat, this is my body,' and there was a Pow! I mean, I knew it had to be more than a gunshot," he said, according to the Las Cruces Sun News. "It didn't know if it was a shotgun blast, I didn't know what. But it was very loud, and I just kept on saying the words."

The blast at Holy Cross shattered windows, while the explosion at Calvary Baptist mainly shredded paper, witnesses said to the Las Cruces Sun News. Trujillo told the Las Cruces Sun News that they are working under the assumption the two explosions are related.

"Just the fact that they were at churches the same day a half and hour apart or so, that leads us to believe it could be something related," he said.

The FBI said it is too early to determine what happened, reported CBS News. The local bomb squad and the FBI are reportedly working to determine what type of explosive -- if any -- was used. All services at the two churches have been canceled.
