Manama: A Kuwaiti lawmaker has urged the government to keep students away from schools until they are cleaned from the dust and sand that settled in following Friday's huge sandstorms.

"There is real danger to the health of our children from schools that have not been cleaned thoroughly," Faisal Al Mislim said.

"The education minister should send all students home until the schools are fit to receive them," he said.

Kuwait is now faced with the formidable task of dealing with the aftermath of the sandstorms that blanketed the country in thick clouds of fine sand and affected homes and other buildings.

The sandstorms had reduced visibility to zero in some areas and brought road, air and sea traffic to a standstill. Kuwait International Airport was shut down and activities at the seaports were suspended until weather conditions improved.

Eisa Ramadan, the senior meteorologist with the Directorate General of Civil Aviation's (DGCA) meteorology department, said that weather conditions would continue to improve over the next few days, with cool nighttime temperatures and gradually rising moderate daytime temperatures, Kuwait Times daily reported on Sunday.

However, Eisa said that northwesterly winds ranging from 12 to 35 kilometres per hour would affect large areas of the country for the next few days.

Emergency services at the interior ministry said that the personnel had to deal with around 6,000 calls during the storms and afterwards.

Kuwaiti media reported that three people were killed during the massive storms and that four were still missing.
