Question: On what day in 2017 did the chemical attack happen in the country known for its Muslims and people who attempted a large-scale effort at translation?

<P0-S0> Sunni Muslims make up between 69–74% of Syria's population and Sunni Arabs account for 59–60% of the population. <P0-S1> Most Kurds (8.5%) and most Turkoman (3%) are Sunni and account for the difference between Sunnis and Sunni Arabs, while 13% of Syrians are Shia Muslims (particularly Alawite, Twelvers, and Ismailis but there are also Arabs, Kurds and Turkoman), 10% Christian (the majority are Antiochian Greek Orthodox, the rest are Syrian Orthodox, Greek Catholic and other Catholic Rites, Assyrian Church of the East, Armenian Orthodox, Protestants and other denominations), and 3% Druze. <P0-S2> Druze number around 500,000, and concentrate mainly in the southern area of Jabal al-Druze.President Bashar al-Assad's family is Alawite and Alawites dominate the government of Syria and hold key military positions. <P0-S3> In May 2013, SOHR stated that out of 94,000 killed during the Syrian Civil War, at least 41,000 were Alawites.Christians (2.5 million), a sizable number of whom are found among Syria's population of Palestinian refugees, are divided into several sects: Chalcedonian Antiochian Orthodox make up 45.7% of the Christian population; the Catholics (Melkite, Armenian Catholic, Syriac Catholic, Maronite, Chaldean Catholic and Latin) make up 16.2%; the Armenian Apostolic Church 10.9%, the Syriac Orthodox make up 22.4%; Assyrian Church of the East and several smaller Christian denominations account for the remainder. <P0-S4> Many Christian monasteries also exist. <P0-S5> Many Christian Syrians belong to a high socio-economic class. <SEP> <P1-S0> russia entered the cwc with the largest declared stockpile of chemical weapons. <P1-S1> by 2010 the country had destroyed 18,241 tonnes at destruction facilities located in gorny (saratov oblast) and kambarka (udmurt republic), where operations have finished, and shchuchye (kurgan oblast), maradykovsky (kirov oblast), leonidovka (penza oblast) while installations are under construction in pochep (bryansk oblast) and kizner (udmurt republic). <P1-S2> by 2016, russia destroyed around 94% of its chemical weapons, planning to completely destroy its remaining stockpile by the end of 2018. on september 27, 2017 russia announced the destruction of the last batch of chemical weapons, completing the total destruction of its chemical arsenal, ahead of schedule.on march 4, 2018, russia was alleged to have conducted a chemical attack in salisbury, uk that left 5 injured including the alleged target of the attack, sergei skripal. <SEP> <P2-S0> The Khan Shaykhun chemical attack took place on 4 April 2017 on the town of Khan Shaykhun in the Idlib Governorate of Syria. <P2-S1> At the time of the attack, the town was under the control of Tahrir al - Sham, previously known as the al - Nusra Front. <SEP> <P3-S0> these attacks resonated with conservative muslims and the problem did not go away with saddam's defeat either, since american troops remained stationed in the kingdom, and a de facto cooperation with the palestinian-israeli peace process developed. <P3-S1> saudi arabia attempted to compensate for its loss of prestige among these groups by repressing those domestic islamists who attacked it (bin laden being a prime example), and increasing aid to islamic groups (islamist madrassas around the world and even aiding some violent islamist groups) that did not, but its pre-war influence on behalf of moderation was greatly reduced. <P3-S2> one result of this was a campaign of attacks on government officials and tourists in egypt, a bloody civil war in algeria and osama bin laden's terror attacks climaxing in the 9/11 attack. <SEP> <P4-S0> The Arabs undertook large-scale efforts at translation. <P4-S1> Having conquered the Greek world, they made Arabic versions of its philosophical and scientific works. <P4-S2> During the Middle Ages, translations of some of these Arabic versions were made into Latin, chiefly at Córdoba in Spain. <P4-S3> King Alfonso X el Sabio (Alphonse the Wise) of Castille in the 13th century promoted this effort by founding a Schola Traductorum (School of Translation) in Toledo. <P4-S4> There Arabic texts, Hebrew texts, and Latin texts were translated into the other tongues by Muslim, Jewish and Christian scholars, who also argued the merits of their respective religions. <P4-S5> Latin translations of Greek and original Arab works of scholarship and science helped advance European Scholasticism, and thus European science and culture.
