Twin brothers who pleaded guilty to detonating makeshift pipe bombs in Pennsylvania have been sentenced to six to 23 months in prison and barred from contact with each other during five years of probation.

The Daily Local News of West Chester (http://bit.ly/2fO1ECy) reports a Chester County judge on Monday accepted guilty pleas by Daniel and Caleb Tate to arson and misdemeanor retail theft charges.

Prosecutors say the twins set off improvised explosive devices on five occasions in rural western Chester County and eastern Lancaster County while home from college in December, imitating stunts they had seen online.

The twins' targets included a mailbox, an Amish phone shed, a produce shed and a well pump shed. No one was injured.

The brothers have apologized, saying they've shamed their families and themselves.
