We're going to wrap up our Turkey live blog coverage for the day. Here's a summary of where things stand:

• At least one protester has been killed and more than 1,000 injured after a week of protests and clashes that began with a sit-in at an Istanbul park on 27 May. A 20-year-old man died in Istanbul when a taxi drove into a group of demonstrators, Reuters reported.

• Police dispersed crowds on Monday using tear gas and moving phalanxes of officers clad in riot gear. The police action only seemed to inflame protest activity, however. Thousands of people demonstrated in Istanbul, Ankara, Izmir and elsewhere. At this writing reports continue to emerge of tear gas use in Ankara and near Taksim square in Istanbul.

• Prime minister Recep Tayyip Erdogan, the focus of much of the protesters' wrath, continued to strike a defiant, dismissive tone as he began a planned three-day trip to northern Africa. He accused the protesters of being terrorists, then said that calm was returning to the country and would be restored by midweek. In a refrain for his administration, he accused the protesters of being anti-democratic. "Some parties were not happy about results of the elections," he said.

• Turkish president Abdullah Gul defended the right of citizens to protest. "Democracy does not mean elections alone," he said. Opposition Republican People's party leader Kemal Kilicdaroglu called on Erdogan to apologize for police brutality.

• Turkey's 240,000-strong Public Workers Unions Confederation and other workers' unions said they would hold a 'warning strike' on June 4-5 to protest the crackdown on what had begun as peaceful protests.

• The Obama administration called for an investigation into "excessive use of force" by police and directly rebutted Erdogan's characterization of the protesters as extremists. The "vast majority of the protesters have been peaceful," the White House spokesman said.
