Reuters reports heavy gunfire and explosions heard in the Yemeni capital, Sanaa, a day after a Saudi-brokered truce.

The gunfire was centred on the Hasaba district, a focal point of fighting in recent weeks between Saleh's forces and
members of the powerful Hashed tribe led by Sadeq al-Ahmar, the news agency said.

Saudi Arabia had brokered a truce between the Hashed tribe and Saleh forces on Saturday, hours before wounded President Saleh flew to the kingdom for medical treatment.
