Campaigners protesting in Nottingham about the state of the environment say further action is planned over the course of the week and have pledged to "bring the entire city to a standstill".
Protesters from a group called Extinction Rebellion protested yesterday and for around an hour in London Road this morning.
Motorists honked their horns out of frustration as the campaigners blocked off one of the city's busiest roads towards Trent Bridge amid heavy rush hour traffic.
Further action is planned over the next few days, the group confirmed, probably during the rush hour. The group say people need to change their habits - take the bus, train or cycle to work and eat less meat.
Nottinghamshire Police confirmed there had been no arrests in connection with either protest.
