Ammon News - The Guardian - Two explosive devices have exploded near a police checkpoint in Giza, on the outskirts of Cairo, wounding six people.

There was no immediate claim of responsibility for the blasts.

The interior ministry said four police officers were wounded. The state news agency Mena quoted the health ministry as saying six people were taken to hospital.

Egypt has seen a wave of protests and violence since the army ousted elected Islamist president Mohamed Morsi last year amid mass protests against his rule.

The army chief, Abdel Fatah al-Sisi, is likely to run for president and is widely expected to win by a landslide in an election due within six months.

A Sisi presidency would be opposed by Morsi's Muslim Brotherhood, which the government has declared a terrorist group. It has launched a security crackdown against the movement, which rose to power after the 2011 uprising that toppled veteran leader Hosni Mubarak.

The Brotherhood denies any links to militants who have carried out attacks, including bombings in Cairo and the killing of an interior ministry official.
