Iran has condemned a string of deadly bombings in the Egyptian capital amid escalation of violence in the North African country.
In a statement issued on Friday, Iran Foreign Ministry Spokeswoman Marzieh Afkham said the blasts, which have left at least seven dead, are aimed at harming Egypts national unity, stability and security.
She stressed the need for national consensus and understanding in order to prevent the eruption of conflict and division in Egypt.
The first bomb attack was carried out when a car bomber struck a security headquarters in central Cairo early Friday, leaving four people dead.
A second blast killed one person in the Dokki District of the capital.
The third blast, which also left one dead, happened near a cinema on the road leading to the Pyramids of Giza.
The fourth blast happened when a convoy of security forces was hit by a bomb planted in a busy street in Cairo. One person was killed in the bombing.
No group has so far claimed responsibility for the Friday blasts, but militants have stepped up attacks against the Egyptian military since the US-backed army ousted the countrys first democratically-elected president, Mohamed Morsi, on July 3, 2013.
Meanwhile, following the blasts, riot police pushed back hundreds of onlookers, some of whom were chanting slogans against the Muslim Brotherhood.
Although the Brotherhood has denied involvement in previous attacks on military targets, it was still blacklisted as a terrorist group after 15 people were killed in a car bomb attack at a police headquarters north of Cairo in December 2013.
