BP says it has temporarily stopped oil flowing into the Gulf of Mexico from its leaking well.
It is the first time the flow has stopped since an explosion on the Deepwater Horizon rig on 20 April.
The well has been sealed with a cap as part of a test of its integrity that could last up to 48 hours.
BP executive Kent Wells said the oil had been stopped at 1425 local time (1925 GMT) and he was “excited” by the progress.
“It is very good to see no oil go into the Gulf of Mexico,” said Mr Wells.
