Turkey: The origins of Turkey's Occupy Gezi movement

The Turkish government is calling for calm, after a fifth day of anti-government protests.

In Istanbul, police forces have been using water cannon to push back protesters.

Turkey's Deputy Prime Minister has apologised for the excessive force against last week's initial demonstrations in the city.

Two people have died as a result of the violence.

Al Jazeera's Andrew Simmons went to talk to demonstrators in Istanbul to find out what's driving the protest movement.
