Lebanon is holding a day of mourning after six people died and dozens were hurt in some of the worst violence for years in the capital, Beirut, writes BBC.

Gunfire broke out on Thursday during a protest by Shia Muslim groups against the judge investigating last year"s huge blast at the city’s port.

Hezbollah, which organised the protest, says demonstrators were fired on by gunmen on rooftops.

They blamed a Christian faction, although the group denies the charge.
