Large numbers of police massed outside as smoke rose from the hotel and shopping complex, which according to its website holds the largest casino resort in the country.

He declared martial law shortly after militants went on a rampage through the southern city of Marawi, which is about 800 kilometres south of Manila.
"The report comes after President Trump labeled the incident a terror attack during his announcement on the U.S.'s departure from the Paris climate accord".
"We ask for your prayers during these hard times", the hotel tweeted.
The U.S. State Department is urging people to avoid the area, which is near the airport.
The SITE Intelligence Group, a US terrorism monitor, said an Islamic State-linked Filipino operative who provides daily updates on the ongoing clashes in Marawi claimed "lone wolf soldiers" of the Islamic State group were responsible for the attack.
The Philippines Red Cross tweeted that it had transported three people from the resort to hospitals.
