CAIRO, July 24 (Xinhua) -- Tensions are running high across Egypt on Tuesday as at least 12 people were killed and dozens injured in targeted attacks amid clashes between supporters and opponents of Egypt's ousted President Mohamed Morsi.
According to the Egyptian Health Ministry, at least 12 people were killed and 86 injured early Tuesday in clashes between pro- and anti-Morsi Egyptians in the vicinity of Cairo University in Giza governorate.
Clashes also occurred at Tahrir Square in Cairo and Rabia al-Adawaeya Square in Nasr City during the day, said the ministry.
Also on Tuesday, at least 12 people -- six security men and six civilians -- were injured in an overnight blast targeting the security department office in Mansoura city of Egypt's Daqahliya governorate, officials told Xinhua.
Eyewitnesses said they saw people killed in the bombing, while no deaths have been officially reported.
Meanwhile, security forces said at least eight police officers and a number of civilians were injured in a grenade attack at a police station in Daqahliya in northern Egypt. Some of the officers are in critical condition.
About 100 people have died in violence since Morsi was deposed and replaced by interim leader Adli Mansour earlier this month.
On Monday, Mansour called for national reconciliation and a new beginning to establish the future of the country.
However, Morsi's detention and the arrest of senior Muslim Brotherhood leaders have further stretched the strained relations between the two sides, diminishing chances of reconciliation.
The Muslim Brotherhood and its Islamic allies have vowed to keep protests until the ousted leader is released and reinstated.
The Muslim Brotherhood accused the military of staging a coup and refused to recognized the interim administration ahead of new elections early next year.
Also on Monday, Morsi's family said it planned to take legal action outside Egypt against the military for kidnapping Morsi, saying they had not heard from the ousted president since his overthrow.
Meanwhile, the United States, Germany, the United Nations and the European Union also called for Morsi's release.
Egypt's interim government said Morsi is in a safe place for his own good.
