Islamic State poured more fighters into Ramadi as security forces and Shi'ite paramilitaries prepared to retake the Iraqi city that fell to the Islamists a week ago in a major setback for the government. In Palmyra, the Syrian air force struck at buildings captured by the Sunni militant group, whose arrival has raised fears that the city's famed Roman ruins will be destroyed. The air force leveled Islamic State "hideouts" and killed a large number of its members around Palmyra's military air base, Syrian state media said. Islamic State has killed at least 217 people execution-style, including children, since it moved into the Palmyra area 10 days ago, according to the British-based Syrian Observatory for Human Rights. Another 300 soldiers were killed before the Syrian city was captured, the monitoring group said. The insurgents reinforced Ramadi on Monday, deploying fighters in preparation for battle against security forces and paramilitary groups advancing on the provincial capital, which lies 110 km (70 miles) northwest of the capital, Baghdad. Iraqi forces have regained ground east of Ramadi since launching a counter-offensive on Saturday, a week after it was overrun, and on Monday retook a rural area south of the city. Police sources said Iraqi forces supported by Iran-backed Shi'ite militia and locally recruited Sunni tribal fighters had retaken parts of al-Tash, 20 km (12 miles) south of Ramadi. Pro-government Sunni tribal fighters, with the help of the army, laid land mines to reinforce their defensive lines around Baghdadi, a settlement northwest of Ramadi which controls access to a major Iraqi air base. Islamic State attacked Baghdadi with seven suicide car bombs on Sunday. In Ramadi, residents said trucks carrying Islamic State fighters arrived on Sunday evening. Local man Abu Saed heard a commotion outside his house in the city's southeastern Officers neighborhood. "I saw two trucks pull up outside with dozens of fighters carrying arms running quickly into nearby buildings and taking cover." Another resident said at least 40 fighters had jumped out of three trucks that arrived in the southern al-Tamim district on Sunday evening.
