The BBC has obtained four separate videos of the aftermath of the attack on al-Seriha. They are very graphic and show bodies lined up in the courtyard of a mosque, covered with shrouds and blankets. The earliest versions of these videos appeared online on 26 October.BBC Verify has established that the image below was taken in the courtyard of the mosque by matching key features, including the steel gate and a satellite dish in the background, to an image of the mosque from Google maps.

BBC Verify studied the video and photographic evidence, counting at least 82 bodies laid out on beds or on the floor.The UN has said that 124 people died the reprisal killings in al-Seriha. A local civil society group, the Gezira Congress, says that figure could be as high as 140.Another piece of evidence uncovered by the BBC Verify investigation is the appearance of freshly-dug earth mounds in the town cemetery.

Mr Ismail had told us that a mass grave had been dug in the graveyard.In satellite photos captured after the attack, these mounds can be seen in a previously unused section of the cemetery. They are not present in satellite images taken in May.

Nathaniel Raymond, Executive Director at the Yale's Humanitarian Research Lab told the BBC that in a separate image taken on 30 October, the graves appear to have been recently dug given the distinct shape of the mounds and the colour of the surrounding earth. In the graphic above, we've shown a satellite image from 6 December which more clearly shows the cemetery.

"These two indicators tell us that the mounds had not been there for likely more than a few days because the edges of the mounds over time will smoothen and become more blurry because of wind and dust," he said.British Foreign Secretary David Lammy called the veto a "disgrace". But Russia accused the UK of meddling in Sudanese affairs without involving Sudan itself.

Sudan's 19-month civil war is believed to have led to the deaths of tens of thousands of people. More than 11 million have been forced from their homes.Aid workers say the conflict has created the world's worst humanitarian crisis, with many thousands at risk of famine.

Sudanese activists have been highly critical of the UN for being slow to respond to the conflict.It began in April last year after the army and a powerful paramilitary group, the Rapid Support Forces (RSF), began a vicious struggle for power.
