A human chain along the German and Polish border to protest plans for a new coal mine.
Some 7,000 people linked hands from the German village of Kerwitz...over the border to the Polish village of Grabice.
Residents of both towns are angry because they could be forced to relocate if plans for the German-Polish energy venture go ahead.

(SOUNDBITE) (German) PROTESTER, RAIMUND KAEMM, SAYING:
"Climate change is becoming a real threat for our children and this is why we should no longer mine brown coal
