Overview

• Turkish authorities have detained 343 people during protests in at least 55 provinces following the arrest of Istanbul Mayor Ekrem Imamoglu.
• Imamoglu, a prominent opposition figure, faces allegations of corruption and ties to the banned Kurdish militant group PKK, charges he denies.
• President Erdogan has warned against what he called 'street terrorism,' as riot police used tear gas and rubber bullets to disperse demonstrators.
• The protests have negatively impacted Turkey's financial markets, with the stock exchange closing down nearly 8% on Friday.
• Imamoglu is expected to appear before prosecutors later today for questioning, as opposition leaders and international observers criticize the charges as politically motivated.
