Question: Does the Syrian government have control over the town where US launched airstrikes that killed dozens pro-Syrian government militiamen? Passage 1:Inside the church are galleries on the north, west, and south sides. These are carried on Tuscan columns, which rise to the ceiling as wooden quasi-Tuscan columns. At the east end of the church are paintings by Jacob Thompson of Penrith dated 1845 depicting the Angel and the Shepherds, and the Agony in the Garden. The communion table dates from 1722, and was lengthened in 1951. The brass chandeliers were given to the church in 1746 by the 2nd Duke of Portland in recognition of the part the town played in the defence against the Young Pretender in 1745. The pulpit consists of the top section of a former three—decker. At the back of the gallery are royal arms dated 1723 by Mathias Read. The font consists of a simple octagonal bowl, and is dated 1661 which is the date it was brought back into use after the Restoration of King Charles II. The stained glass in the east window of 1870 is by Hardman, and that in the north aisle, dating from 1889, is by Burlison and Grylls. Elsewhere are windows by Clayton and Bell, Powell's, G.J.Baguley, and by Cox, Sons and Buckley. The monuments include two coffin lids inscribed with foliated crosses, one dating from the 14th century, the other possibly from the 12th century. There are also two worn stone effigies from the 17th century.
 Passage 2:The Jacob Diamond, also known as the Imperial or Victoria Diamond, is a colorless Golconda Diamond ranked as the fifth-biggest polished diamond in the world. The last Nizam of the Hyderabad State, Mir Osman Ali Khan, found the diamond in the toe of the shoe of his father (Mahboob Ali Khan) at Chowmahalla Palace and used it as a paper weight for a long time. It was bought by the Government of India for an estimated $13 million in 1995. It is cut in a rectangular cushion-cut, with 58 facets, and measures 39.5 mm long, 29.25 mm wide and 22.5 mm deep. The diamond weighs 184.75 carats (36.90 g). Currently, it is kept at the Reserve Bank of India vaults in Mumbai. As part of the Nizam's jewellery exhibition in 2001 and 2007, the Jacob diamond was a major attraction at Salar Jung Museum, Hyderabad.
 Passage 3: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.
