The demonstrations were sparked by a deadly brawl that broke out in the German city of Chemnitz in the early hours of Sunday (August 26). What started out as a war of words resulted in a 35-year-old man being stabbed to death. Hours later, spontaneous, anti-migrant protests took over the streets of Chemnitz.

A German-Cuban man was stabbed in an altercation involving 10 people, several of whom were of "various nationalities," police sources said. The victim, named only as Daniel H., was apparently well-known among various political groups in the area. Two men in their 30s were also stabbed and seriously injured, and a 22-year-old Iraqi and 23-year-old Syrian are in custody over the killing.

By Sunday afternoon, some 800 people had gathered to protest the man's death, including far-right groups. Authorities said the crowd was largely uncooperative and threw bottles at police officers. Police reinforcements had to be called in from nearby cities. The mobilizations were spontaneous and are thought to have surfaced following calls to demonstrate on social media.

German authorities said that that far-right groups spread misinformation on the internet. Among the false claims was that the victim of the knife attack died protecting a woman.

Thousands of far-right and counterdemonstrators faced off in a second day of protest Monday. Several people were injured as objects and fireworks were hurled. Video footage showed the far-right "Pro Chemnitz" movement holding a banner with a quote from early 20th century poet Anton Günther reading "German and free we aim to be."

Counter-demonstrators denouncing right-wing extremism also took to the streets of Chemnitz. Among the protesters were Antifa, who clashed with right-wing demonstrators.

At least 6,000 people gathered in the heart of western German coal country Saturday to demand an end to coal use. People from around the world joined forces with a local movement that started back in 2012 with a handful of activists trying to stop the expansion of a brown coal mine and save the last 200 hectares of the millennia-old Hambach Forest. The message was clear: Coal is a global problem.

The protestors spanned many ages and walks of life. There were young activists dressed in wigs or hazmat suits, but also families and the elderly. People with reduced mobility followed the march at their own pace. A nine-year-old boy was keen to voice his view on the dirty fossil fuel, telling DW he was worried about his future but expected the authorities to do the right thing and give up coal.

Demonstrators split up, some continuing the authorized protest while others took direct action to block coal infrastructure. A hundred people tried to stop the diggers at two nearby coal mines; close to 40 people were arrested. Trying to reach the train line, another 1,000 protestors ended up on the nearby A4 highway, resulting in around 250 arrests. Both the diggers and traffic were stopped.

A third group was determined to block the railway transporting coal from the Hambach mine to the three power plants where it is destined to be burned. They had their work cut out, with police attempting to block the activists from approaching the railway. In the end they had to change their route several times, running through fields and navigating dense forest to reach their target.

On route to the rail lines, there were no major clashes with police but the atmosphere was extremely tense. Police officers on horseback followed protesters up to the edge of the forest, preventing them from changing course. Outbreaks of nerves rippled through activists and horses — without it being clear who triggered what.

Once the protesters entered the forest, the situation became more fraught. They had to walk carefully to avoid tripping over branches while dodging the police — who physically shoved them as they approached — or each other as, from time to time, the crowd suddenly surged without warning.

In the midst of the chaos, activists called for calm, shouting to one another to stick together and remain peaceful. They held on to each other so no one would fall, get lost, or get caught by the police. Others conferred over the best route to proceed toward the rail line.

Eventually, thousands of protesters arrived at the rail lines. Police officers initially tried to prevent them from climbing down on the tracks, but they were outnumbered. Activists had hung guide ropes down the slopes beforehand, but most people simply slid, ran or tumbled down the bank. Within just a few minutes, the railway was engulfed in a crowd of protestors.

After an exhausting two-hour scramble, protesters sat down for a rest. The weather was bitingly cold, but there was an air of cheer as the crowd made itself comfortable on the tracks. For now at least, the energy companies couldn't transport coal from mines to their power plants — a victory celebrated under the watchful eyes of police on the hills above.

The police warned that the direct action was illegal, and offered protesters the chance to abandon their blockade without penalties. But most stayed put overnight. Organizers said their protest blocked coal infrastructure for around 24 hours — which they judged a success. The last 50 to leave the protest had chained themselves to the tracks and had to be forcibly evicted one by one.
