Sirens sounded and authorities posted several alerts on social media urging residents to seek shelter, their first warnings since September.

After a lull in attacks, Bahrain, which hosts a major US naval base, has been targeted twice in three days. The energy-rich Gulf has borne the brunt of Iranian strikes during the war.

Bahrain's military said it intercepted several Iranian attacks, "preventing them from reaching their intended targets". The foreign ministry said air defence systems shot down Iranian drones.
