The Saturday explosion in eastern Cairo came as Egyptian authorities reported that yet another bomb was defused at the same station.

Since the US-backed Egyptian army ousted the nation’s first democratically-elected president Mohamed Morsi in July, militants in the country have stepped up attacks against the security forces, killing a number of soldiers and police officers.

Attacks against civilian targets in the country, however, have been rare.

In February, a bomb that struck a bus carrying tourists near the Taba border crossing in South Sinai killed three South Koreans.

The Al-Qaeda-inspired Ansar Beit al-Maqdis claimed responsibility for the terrorist attack.
The group has also claimed responsibility for other high-profile attacks, including a car bombing at a police headquarters in Cairo and the shooting down of a military helicopter in the Sinai Peninsula.

The Sinai-based group claimed the attacks were in revenge for a deadly crackdown by the military-installed government forces on Morsi supporters.

Muslim Brotherhood supporters of Morsi, however, have fiercely denied any connection with terrorist attacks after being accused and labeled as a terrorist group by the country’s interim government that came to power following Morsi’s forced ouster.

More than 1,4000 people have been killed during the Egyptian military crackdown on pro-Morsi protesters, according to Amnesty International. Thousands more have been imprisoned.
