On Friday, militants opened fire and set off explosives across Paris in a coordinated attack that has left 129 people dead and 352 injured. The deadly assault occurred as Lebanon mourned 43 people who were killed and 239 injured by a suicide bombers in Beirut the previous day.

Both horrifying acts have been claimed by the Islamic State (ISIS).

As updates and news of the massacre came out late last night, messages of shock, sadness, and support flooded Reddit—along with fear over how backlash from the tragedy could be misdirected at Muslims.

Others emphasized that fears generated by terrorism are shared by all. Reddit user Ten1a shared concerns about how things could get worse:

“I have no idea how the world will be in a few short years. I worry that my baby might die in a terrorist attack, that my family and friends (non-Muslims and Muslims alike) might get caught up in an attack. It doesn’t bear thinking about—but I don’t think my fears about my loved ones are unique to me as a Muslim. So my short answer is, very sad and very afraid.”

Still, there were many who expressed solidarity. Some related the situation to terrorist attacks committed by other religious and ethnic groups in past and the aftermath that followed.

“I’ve been in their shoes,” Reddit user wagonloadsbarkless writes, describing his experience growing up as an Irish Catholic in England during the era of the Irish Republican Army (IRA). He says as a result he always goes out of his way to be friendly and encourages others to offer their support:

“In the same way I had no control over the bastards who, supposedly, acted in my name I know they have no control over the excrement who act, supposedly, in theirs. It’s not much in the great scheme of things but perhaps it will make one persons day a little easier and sometimes that is the best we can do.”
