Syria army units clash as crackdown intensifies
Syrian army units have clashed with each other over following President Bashar Assad's orders to crack down on protesters in Daraa, a besieged city at the heart of the uprising, witnesses and human rights groups said.
More than 450 people have been killed across Syria - about 100 in Daraa alone - and hundreds detained since the popular revolt against Assad began in mid-March, according to human rights groups. (AP)
