Oil jumped after Saudi Arabia, Egypt, the United Arab Emirates and Bahrain cut ties with Qatar on Monday while sterling slipped after the weekend attacks in London that killed at least seven people and wounded 48, just days before Britain's general national election.
The coordinated move by the Middle Eastern countries, accusing the wealthy Gulf Arab state of supporting terrorism, dramatically escalates a simmering dispute over Qatar's support for the Muslim Brotherhood, the world's oldest Islamist movement.
