His comments came after reports that at least 94 people were killed when Egyptian security forces entered two camps in Cairo, where supporters of deposed president Mohamed Mursi held a protest against the transition government currently ruling Egypt.
Asked whether the European Union will intervene, Bildt said:
"We have limited possibilitites to do that. You have to be aware that developments in Egypt to a large extent follow their own logic. When they themselves do not want to have a dialogue, it is hard for us to achieve dialogue."
"But we will try in any way possible to say that the only possible solution to Egypt's political problems and confrontation is for them to take a step back from the abyss - to talk to each other and find a political solution," he added.
