Explosions and gunshots were heard at an entertainment resort in the Philippines capital Manila early on Friday and armed police were deployed to the scene, local media reported.
Police and fire services could not immediately be reached for comment.
Pictures circulated on social media of the resort, close to the city's airport, of plumes of smoke pouring out of a building.
A source at one of the resorts told Reuters employees were being evacuated and declined to give more details. He said police were now in full control of the situation.
