Beirut police fire teargas at protest by relatives of blast victims

Protestors marched in a symbolic funeral procession with empty coffins to symbolise people killed in Lebanon blast

Lebanese riot police have fired teargas and scuffled with protesters and relatives of those who died in last year's Beirut port blast amid growing anger at what they call the obstruction of an investigation into one of the largest non-nuclear explosions in history.

The unrest took place on Tuesday after hundreds of protesters gathered outside the home of Lebanon's caretaker interior minister, Mohamed Fehmi, weeks away from the first anniversary of the Beirut explosion approaches.
