Kuwait says its ruling 90-year-old emir has left a US hospital after having "successful checkups" that forced him to cancel a visit to the White House.
The state-run KUNA news agency reported early Friday that Sheikh Sabah Al Ahmad Al Sabah's checkups "showed reassuring results."
That came after visiting Iranian Foreign Minister Mohammad Javad Zarif wrote on Twitter that he was "praying for emir's speedy recovery."
