A judge in Cairo has adjourned the trial of deposed Egyptian President Mohamed Mursi along with 14 members of the Muslim Brotherhood.
Proceedings were delayed by two hours after Mursi refused to wear a prison uniform, part of his refusal to recognise the court.
Once the hearing did get underway, the judge then had to halt the trial after chants by the defendants proved too disruptive to continue.
Mursi is facing charges of inciting the killing of protesters outside the presidential palace as opposition to his rule spread earlier this year.
Mursi replaced Hosni Mubarak as Egyptian president following a democratic election, but over the course of his 13-month rule he fell into conflict with a number of key institutions.
As discontent spread, the army stepped in and removed him from power in July.
Since then the interim government has cracked down on the Muslim Brotherhood and has arrested hundreds of its members.
Cairo is on edge and many believe the trial will further deepen divisions within the country and lead to yet more instability and violence.
