Houthi militants have issued a decision banning Yemen’s ex-president Ali Abdullah Saleh, leaders of his party and lawmakers from leaving Sanaa.

The militants set up checkpoints near Saleh's residence, Arabic-speaking Sky News channel reported on Sunday, quoting Yemeni media sources.

Earlier, Houthis have dispatched 30 military vehicles to al Sabeen Square in the capital.

The decision came on the back of ongoing clashes between Houthi militants and Saleh supporters in Sanaa.
