Kuwait's Minister of Public Works, Hussam al-Roumi, resigned Friday because of the huge damage to public property caused by heavy rains and floods, the state news agency KUNA.
"Out of my moral responsibility ... I have submitted my resignation to the President (Kuwaiti Emir)," al-Roumi said.
He expressed apologies to citizens and expatriates for damage they incurred, voicing gratitude to Emir Sheikh Sabah al-Ahmed al-Jaber al-Sabah, Crown Prince Sheikh Nawaf al-Ahmed al-Jaber al-Sabah and Prime Minister Sheikh Jaber al-Mubarak al-Hamad al-Sabah for their support.
He stressed that he had exerted every effort to preserve public funds and fight corruption, as well as improve work in the ministries he held.
Footage posted on social media from across Kuwait showed torrents sweeping away cars as sewage systems failed to drain the heavy downpour.
The prime minister said earlier that the government was following up closely on the situation across the country.
Public officials failing to fulfill their duties will be held accountable, he vowed.
Kuwait's army and National Guard joined rescue efforts, KUNA said.
The meteorological department of Kuwait's Directorate General of Civil Aviation reported that the country has received 29.63 millimeters since Thursday evening, a significantly high amount for Kuwait in a 24-hour span.
The unstable weather is expected to last until Sunday morning.
