Climate activists block runways at 2 German airports, disrupting flights for hours – Climate activists blocked flights at two German airports for several hours Thursday in protest against the most polluting form of transportation, and to demand tougher government action to reduce greenhouse gas emissions.

The group Last Generation said several of its members entered the grounds of Hamburg Airport around 6 a.m. (0400 GMT) and glued themselves to the runway on the first day of the school vacation in the north German city.

Dozens of flights were canceled and 10 arrivals had to be diverted to other airports, Germany’s dpa news agency reported.
