ISTANBUL — Taksim Square is mostly back to normal: the taxicabs line up in front of fancy hotels, whose doormen no longer clutch gas masks, and outdoor cafes are bustling again.

But Gezi Park — the green corner of the square — remains occupied by defiant protesters who on Friday mostly disavowed a compromise between their self-declared leaders and Prime Minister Recep Tayyip Erdogan to end a political crisis that has been punctuated by bouts of street violence that have severely damaged Turkey’s image, and its economy.

After a booming thunderstorm Friday morning, organizers who in the early morning hours had walked out of Mr. Erdogan’s home in Ankara, Turkey’s capital, with a tentative deal to end the protests were met with defiance by the rank-and-file protesters who populate the tent city the park has become.

“Cowards! Liars! Sheep!” shouted some protesters as members from a group called Taksim Solidarity, an umbrella group that originally mobilized people to protest a government plan to demolish the park, tried to deliver details of their meeting with Mr. Erdogan.
