Belgium's capital, Brussels, entered lockdown this weekend as authorities swept the city for suspected terrorists, including at least one high-profile fugitive wanted in connection with the Paris attacks. On Twitter, authorities prompted residents to refrain from posting pictures or information about ongoing police movement -- and Belgian residents obliged, with a twist. They flooded the hashtag #BrusselsLockdown with pictures of cats, making information about raids harder to find and showcasing the country's solidarity against terrorism. On Monday, as the city remained under its highest-level terror alert, Belgian federal police thanked residents on Twitter with a picture of cat food and the message, "For the cats who helped us last night... Help yourself!"
