Hundreds of Turkish police officers blocked access to the main opposition party’s Istanbul headquarters, as a court appointee prepares to take over its local leadership in a mounting political stand-off.

Republican People’s Party officials called the blockade a “siege” and rallied supporters around the building on Sunday night, defying a three-day ban on demonstrations announced by the provincial governor’s office in six districts of the city.
