question:
Question: Does the Syrian government have control over the town where US launched airstrikes that killed dozens pro-Syrian government militiamen? Passage:Tensions between the Syrian Army and the Syrian Democratic Forces in the eastern bank of the Euphrates of Deir ez-Zor Governorate have always been high following the liberation of Deir ez-Zor city from ISIL and the SDF's capture of large parts of the area following its offensive against ISIL with CJTF–OIR support. On 16 September 2017, either Syrian or Russian aircraft bombed SDF positions on the eastern bank. On 25 September, Russian and Syrian forces shelled SDF forces in the nearby Conoco gas field. Between 7 February and 8 February 2018, clashes between the SDF and pro-Syrian government forces near Khasham resulted in US airstrikes on pro-government forces which killed dozens of pro-government militiamen, allegedly including contractors of the Russian private military company Wagner Group. Additional armed incidents took place in the following weeks.

question:
Question: How long is the river along which the Polanie remained in situ? Passage:The Poles are the most numerous of the West Slavs and occupy what some believe to be the original homeland of the Slavic peoples. While other groups migrated, the Polanie remained in situ along the Vistula, from the river's sources to its estuary at the Baltic Sea. There is no other European nation centred to such an extent on one river. The establishment of a Polish state is often identified with the adoption of Christianity by Mieszko I in 966 CE (see Baptism of Poland), when the state covered territory similar to that of present-day Poland. In 1025 CE, Poland became a kingdom. In 1569, Poland cemented a long association with the Grand Duchy of Lithuania by signing the Union of Lublin, forming the Polish–Lithuanian Commonwealth. The Polish–Lithuanian Commonwealth was one of the largest and most populous countries in 16th- and 17th-century Europe.

answer:
While other groups migrated, the Polanie remained in situ along the Vistula, from the river's sources to its estuary at the Baltic Sea

In November 1987 he scored 10–5 from the maegashira 6 ranking, defeating two ōzeki and winning the Technique Prize. This earned him promotion to his highest rank of sekiwake for the following tournament in January 1988. However, by the end of the year he was in jūryō again due to injury problems. He won the jūryō yūshō on two occasions in 1989 and won promotion back to the top division.
