(Reuters) - Renewed fighting in Yemen's capital between a powerful tribal group and President Ali Abdullah Saleh's forces has killed at least 19 people this week and rocked Sanaa with explosions, officials said on Wednesday.

World powers have been pressing Saleh to sign a Gulf-led deal to end his three-decade rule and stem spreading chaos in unstable Yemen, a haven for al Qaeda militants and neighbor to the world's biggest oil exporter,Saudi Arabia.
