* Students throw stones at Darfur peace negotiators
* Tour by mediators shows Darfuris' anger
* Darfur peace talks stalling

ZALENGEI, Sudan, Dec 1 (Reuters) - Hundreds of angry students threw stones at Darfur mediators, including the Qatari foreign minister, on Wednesday during a tour of the turbulent region that has been marred by violence and demonstrations.
Wednesday's violence was the second time in two days the team negotiating peace between Darfur's rebels and the government had to flee angry Darfuris, frustrated by the absence of a peace deal after years of conflict.
The United Nations estimates 300,000 people died in a humanitarian crisis in Darfur caused by a government counter-insurgency campaign that Washington has branded genocide. Khartoum puts the death toll at 10,000.
Round after round of peace talks have been dogged by military clashes and divisions among the rebels. The two main insurgent groups are not participating in the latest negotiations hosted by Qatar.
Two Reuters journalists travelling with the delegation saw the mediators blockaded into the university in Zalengi by a mob of angry students.
"Bassole is a foreign agent," many shouted, referring to the chief mediator, Djibril Bassole.
When the delegation eventually managed to leave, the students threw stones at their convoy and hit the cars with sticks, breaking the windows of two U.N. cars. Sudanese police then fired into the air.
Zalengei, in West Darfur, is a stronghold of rebel leader Abdel Wahed Mohamed el-Nur.
On Tuesday, the delegation, including Bassole and Qatari Foreign Minister Ahmed bin Abdullah al-Mahmoud, had to flee after angry civil society activists stormed a meeting in South Darfur's capital Nyala, insisting they also be heard.
U.N.-African Union peacekeepers restrained the activists and rushed the mediators to safety outside the meeting room.
The demonstrations illustrate the anger of Darfuris, who feel neglected after repeated promises by successive international delegations that peace is coming.
More than 2 million Darfuris have fled their homes and are languishing in miserable makeshift camps.
