OMAHA, Neb. (AP) — Several Nebraska churches have strengthened security around weekend worship services, and some have even added armed guards, because of worries about church shootings that have happened elsewhere.

Church leaders say they are taking precautions and aren’t responding to any specific threats. Shootings in recent years give church leaders reason to be wary.

Jim Nichols is security director at King of Kings church in west Omaha. He says any church’s worst fear is a mass shooting.

At King of Kings, security team members wear uniforms and an armed guard stands near the back of the worship hall in west Omaha. Another volunteer monitors security cameras.
