MOSUL (Reuters) - Iraqi special forces and police fought Islamic State militants to edge closer to the al-Nuri mosque in western Mosul on Wednesday, tightening their control around the landmark site in the battle to recapture Iraq's second city, military commanders said.
The close-quarters fighting is focused on the Old City surrounding the mosque where Islamic State leader Abu Bakr al-Baghdadi proclaimed a caliphate nearly three years ago across territory controlled by the group in both Iraq and Syria.

"Federal police forces have imposed full control over the Qadheeb al-Ban area and the al-Malab sports stadium in the western wing of Old Mosul and are besieging militants around the al-Nuri mosque," federal police chief Lieutenant General Raed Shaker Jawdat said in a statement.
Rapid Response elite interior ministry troops were advancing on the edge of the Old City, clambering over garden walls. Islamic State responded with rocket fire, streaking the sky with white smoke plumes.
"There are teams going into the Old City since yesterday," said Rapid Response official Abd al-Amir.
Iraqi troops shot down at least one suspected Islamic State drone. The militants have been using small commercial models to spy and drop munitions on Iraqi military positions.
With the battle entering the densely populated areas of western Mosul, civilian casualties are becoming more of a risk. The United Nations says several hundred civilians have been killed in the last month, and residents say Islamic State militants are using them as human shields.
Iraqi military command has said one line of investigation is whether Islamic State rigged explosives that ultimately caused the blast that destroyed buildings. Iraqi military said there was no indication the building was hit directly by the strike.
