Residents in Diyarbakir, Turkey's largest Kurdish-majority city, said on Sunday that the outlawed Kurdistan Workers Party's (PKK) decision to heed its jailed leader's call for peace was correct and prosperity would follow if the decades-old conflict ended.

The mountains of northern Iraq have for years been a sanctuary for Kurdish militants fighting a decades-long insurgency against the government in neighboring Turkey.

The group, the P.K.K., made its declaration days after its long-imprisoned leader urged the movement to disarm and disband, but there are still many questions about the prospects for ending 40 years of deadly conflict.
