Thanks.
So there wasn’t one attack that killed 126? Am I understanding your comments accurately?
Yes, there was ONE explosion that killed 126.
There was also some artillery shelling that injured two Russian news reporters:
... shells fired by the Islamic State group (ISIS) on government-held parts of the eastern city of Deir el-Zour wounded two members of a Russian media delegation visiting the area, according to state-run Syrian news agency SANA.
Russia's Anna-News military news service, which employs the journalists, said one was wounded in the arm while the other suffered leg and stomach wounds. The news service said the two were evacuated adding that their condition was "satisfactory."
Also, a coalition airstrike killed 8 within a few hours of the 126, but at a separate but nearby location:
In eastern Syria, an airstrike by the U.S.-led coalition on the village of Sukkarieh near the border with Iraq killed eight civilians who had earlier fled violence in the northern province of Aleppo, according to Deir Ezzor 24, an activist collective, and Sound and Picture Organization, which documents IS violations.
