South Africa faces crisis over immigrant attacks

JOHANNESBURG — South Africa’s president on Saturday canceled a foreign trip in order to deal with a wave of attacks on immigrants that have killed at least six people. In the latest violence, mobs attacked shops owned by foreign nationals in a poor area of Johannesburg.

President Jacob Zuma had been scheduled to leave Saturday evening for Indonesia to attend a meeting of African and Asian leaders, but will instead stay to campaign for a peaceful resolution to the unrest, his office said.
