Snipers in high-rise buildings are the main problem facing Philippine forces battling to crush pro-Islamic State fighters who have occupied a southern city for more than a month, a military spokesman said Saturday. Lieutenant Colonel Jo-ar Herrera said this was the reason the government was using air strikes against the militants despite the massive damage it may cause in the city of Marawi.
"If we do not use air strikes, we will incur more casualties of our troops," he told reporters in Marawi, which was overrun by hundreds of militants on May 23. Despite more than a month of fighting with hundreds of government troops, militants flying the black flag of the Islamic State group are still entrenched in parts of the city. The military has used jet fighters, attack planes and helicopter gunships, armed with bombs and rockets, to attack areas where the gunmen are hiding. "We have identified key defensive positions. These are being subjected to surgical air strikes now. They are still occupying high-rise buildings.
