Embassies attacked as film protest escalates

Demonstrators yesterday attacked the US embassies in Yemen and Egypt in protest at a film they consider blasphemous to Islam, and US warships headed towards Libya after the US ambassador there was killed in related violence this week.

In Libya, authorities said they had made four arrests in the investigation into the attack that killed ambassador Christopher Stevens and three other Americans in Benghazi on Tuesday.

President Barack Obama has vowed to bring to justice those responsible for the Benghazi attack, which US officials said may have been planned in advance.
