The police have declared DusitD2 hotel and the area around 14 Riverside Drive a no-go zone for members of the public, including politicians.
In a statement, the National Police Service said the area is an active crime scene.
About six armed militants raided the hotel on Tuesday leaving several dead. The police are yet to give an official toll of deaths.
“Until it is declared safe, everyone not actively involved in the operation should avoid the area,” the police said.
