A city's bus route has been temporarily halted after the service was subjected to "vandalism attacks".
Newport Bus, the city's main bus operator, saw three vehicles out of action while they waited for new windows to be fitted after stones were thrown.
A driver was also hit with a stone during one of the attacks.
As a result, the operators have stopped some of the services to the area for a few days.
Newport Bus said: "This decision has been made in consultation with senior staff and has been made in the interest of the safety and wellbeing of our staff and customers.
"The potential ramifications of such incidents are serious. It has been due to good fortune that someone has not been seriously injured in previous attacks.
"Services will return to normal routes on Friday, September 20, but should further issues occur the company may make the decision to remove these services for a longer or more permanent period."
Newport Bus managing director, Scott Pearson, said: "My main concern is for the safety of the our drivers and customers.
"We have started pulling services out of the area in the evening, for two days only at present, to raise awareness as much as for safety.
"We are working closely with Gwent Police who will be providing extra resources in the areas and on the buses.
"The consequences of these actions also mean that the number of available vehicles in our fleet is being reduced, affecting services all around the city."
Gwent Police are investigating anti-social behaviour in the Ringland area of Newport.
