Aleppo, Syria — Syrian warplanes, artillery and mortar rounds pounded areas in eastern Aleppo on Saturday drawing rebel rockets, as government troops gain new ground in the shrinking opposition-held enclave.

After four years of holding nearly half of the divided city, rebel fighters have been increasingly squeezed into the center of the eastern enclave. Government and allied troops, including Lebanese, Iraqi and Iranian fighters, have concentrated their fight on the northeastern part of the enclave, swiftly taking new districts since their offensive began last week. Another front on the southern outskirts of the city has been slower, as rebel fighters push back government advances there.

The advances have caused massive displacement. The U.N. estimated that more than 31,000 have already fled their homes, either to government or Kurdish areas, or deeper into the besieged enclave. The fighting has also intensified the rebel shelling of government-held areas in Aleppo.

The state broadcaster al-Ikhbariya said “precise operations” by government and allied troops aim to rout out “terrorists,” which is how the government refers to all armed opposition groups.

The sound of war prevailed in the city early Saturday. Warplanes made several runs overhead, drawing what appeared to be rebel machine gun fire toward the aircraft.

The Russian Interfax news agency report quoted an unnamed Syrian military official as saying that a light ground attack aircraft, L-39 jet, was shot down near Aleppo, and its crew was killed. The opposition Britain-based Syrian Observatory for Human Rights, which relies on a network of activists on the ground, said two pilots were killed when rebel fighters targeted the aircraft as it approached Aleppo airport to the east of the city.

Syrian army spokesman Brig. Gen. Samir Suleiman said the Syrian army has regained control of 45 to 50 percent of east Aleppo, and accused insurgents of hiding among civilians. Syria’s Defense Minister and other officers visited newly captured areas in Aleppo on Saturday, according to state-run media. The Syrian Civil Defense in eastern Aleppo said six people were killed in bombings of the central al-Shaar neighborhood. Opposition news agency Thiqa also put the death toll at six. The Britain-based Syrian Observatory for Human Rights put the death toll at three, adding it was likely to rise. In government-held Aleppo, rebel shelling killed five people, according to the state news agency SANA.
