The United States' intensive strikes on Yemen's Houthis have reportedly killed at least 15 people, including children, according to the Houthis.

Additionally, nine others have been injured as a result of the US strikes on Yemen's capital, Sanaa, according to the Houthi rebels' Health Ministry.

Earlier, US President Donald Trump ordered "powerful" and "decisive" military strikes against the group, ordering them to halt their assaults or face severe consequences immediately.
