BERLIN (REUTERS) - Eleven climate activists glued themselves to the asphalt of the German capital's main motorway, causing rush hour traffic jams on Monday (Feb 7), in the latest protest demanding a law against food waste and cuts in greenhouse gas emissions from agriculture.

Activists from the group "Last Generation", who also placed food on the A100 motorway that had been discarded earlier, previously blocked roads and motorways in Berlin, Hamburg and Stuttgart on several occasions last week.

A video showed some frustrated motorists getting out of their cars and pulling activists out of the way by their hoods and backpacks to allow vehicles to pass.

There will be further blockades in other German cities later on Monday, Last Generation said in a statement.

By 1000 GMT, activists had blocked three motorway entrances in three places in Berlin and made one unsuccessful attempt, a police spokesman said.

So far, 27 activists had taken part in blockades, 11 of whom glued themselves to the asphalt, the spokesman said.

Police on Monday were verifying the activists' identities and checking if they could be placed in custody, the spokesman added.

She said she could not immediately say how many people had been detained since the beginning of the protests. According to information from the group's website, there were 50 people in custody in different German cities by the end of the day last Friday.

"By planning to achieve climate neutrality by 2045, the German government breaks its constitutional obligation to protect our lives," said activist Carla Hinrichs in a statement.

"By 2030, we will exceed 1.5 degrees (average rise in global temperatures). The government is not only breaking international law but committing a crime against humanity by deliberately heading for a world hotter by 2, 3, 4 degrees with billions dying of hunger," said Ms Hinrichs.
