Shiite rebels armed with knives and batons have attacked and detained demonstrators trying to protest against them in Yemen's capital.

The Houthi rebels seized Sanaa in September and last week put the president, prime minister and top Cabinet members under house arrest.

On Monday, Houthi militiamen attacked protesters and journalists at Sanaa's Change Square. It wasn't clear how many people they detained, though witnesses said they saw rebels attack those gathered there.

Last week, the standoff in the capital grew violent and Abed Rabbo Mansour Hadi resigned as the country's president. His Cabinet also resigned, though parliament has yet to accept their resignations.

In the time since, demonstrations against the Houthis have grown across the country.
