Russian terror bombing of Ukraine continues. Ukraine's allies donate generators but not long range missiles to strike Russia's capacity to terrorize. Western media ignore the humanitarian disaster altogether.
Ukraine was rocked by a massive overnight Russian assault, with hundreds of drones and dozens of missiles slamming into the country’s energy system.

Rescue and recovery operations are continuing across the country.

A daily reminder that #RussiaIsATerroristState
Another round of peace talks took place tonight. The results are on the map. Rocket and drone explosions in Kyiv, Kharkiv, Odesa, and many other cities all night. In the morning, electricity and heat were out in many areas.

A daily reminder that #RussiaIsATerroristState
Women and children jumping out of a burning train is russia’s new ‘achievement.’ As well as another 5 victims of their deliberate terror.

russia is not a state that can be reasoned with.
It is a state that must be stopped from committing war crimes.

Russia is committing genocide by destroying infrastructure and freezing Ukranian cities, while pretending to have constructive negotiations about peace

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

En Iran, la répression se poursuit.

Après les massacres, les autorités imposent désormais une répression coordonnée et militarisée à l’échelle nationale.

La communauté internationale doit réagir immédiatement !👇
« Ils tirent à balles réelles » : En Iran, un massacre sans précédent contre les manifestations
L’Iran est marqué par une nouvelle vague de manifestations, violemment réprimées par les autorités iraniennes. Au moins 28 personnes ont été tuées, des centaines ont été blessées et arrêtées arbitrairement. L'impunité doit cesser.

On his famous H.M.S. Beagle voyage, Charles Darwin collected this fungal specimen, which would later be used to describe the new species Daedalea erubescens. It was on this same voyage that Darwin began developing his emerging hypotheses on the theory of evolution and natural selection.
