They called on the protesters and the Transitional Military Council to "reach an agreement ASAP on an interim government that is truly civilian-led and reflects the will of the Sudanese people," Nagy tweeted.
"We also expressed concern about the recent violence directed by security forces against protesters, and agreed to call for the TMC to allow peaceful protests and hold accountable those responsible for recent violence," he wrote.
Countries involved were Britain, France, Germany and Norway as well as Ethiopia, which is the chair of an eight-nation Horn of Africa regional bloc, the Intergovernmental Authority on Development, which includes Sudan.
Protesters have remained camped out, saying that they want a rapid transition to democracy rather than continued military rule.
The generals and protest leaders had been expected to come to an agreement on Wednesday on the thorniest issue -- the make-up of a new body to govern Sudan for three years.
