EU Foreign Ministers have agreed to suspend the supply of military weapons to the Egyptian government. The decision came at an emergency meeting in Brussels today to discuss the situation in Egypt.
European countries are also suspending some aid to Egypt but said they would continue offering aid to the most vulnerable there.
The European Union foreign affairs commissioner Catherine Ashton said countries would also consider blocking further exports to Egypt.
"Member states have agreed to suspend export licenses to Egypt of any equipment used for repression, and to re-assess their export licenses covered by their EU common position" she said.
Speaking before the talks in Brussels, Ms. Ashton said there were not many options on the table.
Meanwhile the Tanaiste Eamon Gilmore has said he has no information of any charges that have been brought against Irish citizens in Egypt.
Speaking before the EU gathering, Mr. Gilmore said he is concerned at reports of charges against four members of the Halawa family.
Nearly 900 people have died in a week of clashes between security forces and Islamist supporters of the Muslim Brotherhood.
The bloodshed peaked in Cairo last Wednesday when the army stormed two camps of supporters of the ousted President Mohamed Morsi.
The arrest of the supreme guide to the Muslim Brotherhood, Mohamed Badie, yesterday has also raised fears of fresh unrest.
Sister says charges are 'ludicrous'
Meanwhile, the sister of the four Halawa siblings being held has described the charges apparently facing them as "ludicrous".
The three sisters and their teenage brother from Dublin are expected to be held for another two weeks as an investigation continues into charges including attempted murder and arson.
Nusayba Halawa insisted to Newstalk Breakfast earlier that her sisters and brother have done nothing wrong.
