Task: Question Generation
Input (English): Passage: As a result of the Syrian Civil War, Palmyra experienced widespread looting and damage by combatants. In 2013, the façade of the Temple of Bel sustained a large hole from mortar fire, and colonnade columns have been damaged by shrapnel. According to Maamoun Abdulkarim, the Syrian Army positioned its troops in some archaeological-site areas, while Syrian opposition fighters positioned themselves in gardens around the city.On 13 May 2015, ISIL launched an attack on the modern town of Tadmur, sparking fears that the iconoclastic group would destroy the adjacent ancient site of Palmyra. On 21 May, some artifacts were transported from the Palmyra museum to Damascus for safekeeping; a number of Greco-Roman busts, jewelry, and other objects looted from the museum have been found on the international market. ISIL forces entered Palmyra the same day. Local residents reported that the Syrian air force bombed the site on 13 June, damaging the northern wall close to the Temple of Baalshamin. During ISIL's occupation of the site, Palmyra's theatre was used as a place of public executions of their opponents and captives; videos were released by ISIL showing the killing of Syrian prisoners in front of crowds at the theatre. On 18 August, Palmyra's retired antiquities chief Khaled al-Asaad was beheaded by ISIL after being tortured for a month to extract information about the city and its treasures; al-Asaad refused to give any information to his captors.Syrian government forces supported by Russian airstrikes recaptured Palmyra on 27 March 2016 after intense fighting against ISIL fighters. According to initial reports, the damage to the archaeological site was less extensive than anticipated, with numerous structures still standing. Following the recapture of the city, Russian de-mining teams began clearing mines planted by ISIL prior to their retreat. Following heavy fighting, ISIL briefly reoccupied the city on 11 December 2016, prompting an offensive by the Syrian Army which retook the city on 2 March 2017.
Output (English): What is the name of the city that was briefly reoccupied by ISIL on 11 December 2016?
