Vandals struck another pro-life pregnancy center over the weekend, breaking windows and writing graffiti on the Hope Pregnancy Center in Philadelphia.

The Catholic News Agency first reported about the crime Wednesday – the latest in a growing string of vandalisms, arsons, threats and other incidents targeting pro-life advocates since news broke in May about a leaked draft ruling showing the U.S. Supreme Court overturning Roe v. Wade this summer.

Latrice Booker, director of Hope Pregnancy Center, told CNA said she discovered the vandalism Saturday and contacted police.

Booker said four windows and three glass doors were broken, and one had indistinguishable graffiti written on it. She told CNA that they will not be intimidated by the vandalism and encouraged pro-lifers to “stand tall” in the midst of the growing hostility.

Despite the damage, she said they have kept their doors open to continue serving families in need. Hope Pregnancy Center provides free counseling, education and material support to help mothers choose life for their babies.
