Kuwait temporarily closed its airspace on Thursday and a child was injured in Bahrain because of an attack by Iran.
Kuwait's air defenses were engaging hostile aerial targets, the army said, while Bahraini air defenses intercepted and destroyed Iranian aerial attacks, a media adviser to Bahrain's king said on X.
Bahrain's Interior Ministry said later Thursday that an 11-year-old girl suffered minor injuries, while vehicles caught fire and homes were damaged in Hamad Town and the capital Manama after debris fell from Iranian drones that were intercepted and destroyed.
The ministry published pictures showing fire fighters trying to put out blaze in several homes.
Kuwait diverted flights to alternative airports after the Iranian attacks in the region.
"This measure comes in light of the Iranian attacks on the State of Kuwait and the potential risks this poses to civil aviation in the region," the Kuwaiti Directorate General of Civil Aviation said in a statement.
"Airspace will be reopened and air traffic will resume as soon as the situation has ended and the causes of the danger have been eliminated, based on the assessment of the relevant authorities."
Jordan's military said it had intercepted 20 missiles launched from Iran.
"At dawn on Thursday, Jordanian air defense systems and the Royal Jordanian Air Force intercepted and shot down 20 missiles that had been launched from Iran towards the Azraq area in Zarqa governorate," a statement quoted a military official as saying, referring to an area about 80 kilometers (50 miles) east of Amman.
