The US Embassy in Kuwait said Monday that people should not come to the facility, as smoke was seen rising from the diplomatic mission on Iran's third day of retaliatory attacks.
"There is a continuing threat of missile and UAV attacks over Kuwait. Do not come to the Embassy. Take cover in your residence on the lowest available floor and away from windows. Do not go outside," the Embassy said in a statement.
"US Embassy personnel are sheltering in place," it added.
The statement came as Kuwait said it intercepted hostile drones.
A series of loud blasts was heard on Monday morning in Dubai and the Qatari capital of Doha. Loud bangs and sirens were heard earlier in Kuwait.
No injuries were reported after Kuwait air defenses intercepted the majority of the drones near Rumaithiya and Salwa neighborhoods, the state news agency cited the director-general of the civil defense as saying.
