Gunfire was reported at a hotel and a casino resort in the Philippine capital on Thursday night, the operator of the complex said, and the Islamic State group quickly claimed responsibility.

'Resorts World Manila is currently on lockdown following reports of gunfire from unidentified men,' the company said on its Twitter account.

Philippine media reports that police, firetrucks and SWAT team are in the area.
