As we learn more about the atrocities committed by the Assad regime, investigations are underway

at sites across that country. Authorities and relatives are trying to uncover the fate of the

many thousands detained and feared murdered during Assad's rule.

Simone Fultein went to visit three mass grave locations today, and she joins us now.

Simone, tell us what you saw.

Well, Jeff, it was quite grim, and these mass graves really bear witness to just how systematic the killing was under Assad's government, and the details are only just beginning

to come out.

The first site we went to was in Tadamun, which is a

suburb in the south of Damascus, and it is known for a massacre that occurred there in 2013,

alongside a series of other extrajudicial executions. Essentially, this neighborhood had been

turned into a killing field.

And when we went there, residents pointed us to several shallow graves that had been dug in between the homes.

We saw human remains and bones sticking out of the ground, children playing on these sites.

So it was quite jarring to see also how accustomed people had become to living

near these mass graves, which haven't been secured at all. Now, the second site we went to was quite different.

It was in a rural area close to the prison of Sait Naya, which has been, as we know by now,

dubbed the human slaughterhouse of Syria.

And this site is probably where many of the thousands of people who perished in Saed Naya

were buried.

It was a lot more organized.

You could tell that the site had been planned out.

It had been segregated into sections.
