BRASILIA: Brazilian President Michel Temer signed a decree Tuesday to send the army to 'guarantee law and order' on the border with crisis-hit Venezuela after recent violent clashes.

Earlier this month, more than a thousand homeless Venezuelan immigrants who had flooded over the border into Brazil's northwestern Roraima state were driven back by an angry mob that rampaged through their makeshift tent following rumours a local shopkeeper had been brutally beaten by migrants.
