A mailbox was blasted at Calvary Baptist Church in Las Cruces, about 100 miles from the Mexico border, around 8 a.m. local time, the police statement said.

‘I didn’t know if it was a shotgun blast, I didn’t know what.

All masses have been canceled. Trujillo said police have advised other churches in the area “to be on the lookout for anything suspicious”.

The two explosions caused relatively minor damage at each location and no injuries have been reported.

Llewellyn said there were about 30 people inside the building when the explosion occurred.

Eyewitness Ann Marie Sullivan, a college student and parishioner at Holy Cross said: ‘I had just received communion and had gotten back to my chair when the police came up and said we need everyone to leave out the doors calmly.’.
