An explosion occurred on Monday in the center of the Egyptian capital of Cairo near the Al-Azhar University, Sky News Arabia television reported.
At least two people were killed and three wounded in an explosion behind Al-Azhar Mosque when a suicide bomber allegedly blew himself up in the capital city, Egypt's ministry of interior confirmed.
Officials said the suspect was being chased by policemen as he was believed to have planted an explosive device last week near a mosque.
The man was being pursued as part of "efforts to search for the perpetrator" responsible for planting an explosive device near security staff close to a mosque in Giza on Friday, the ministry said.More news: Watch Francis Ngannou Knock Out Cain Velasquez In Just 26 Seconds

Egyptian security forces have been waging a campaign against Islamist militants over the past year focused on Egypt's Sinai Peninsula. They said the firefights took place when the security forces stormed their hideouts, but did not say when that happened.
Security had defused the device then, the ministry said.
All officials spoke on condition of anonymity because they were not authorized to talk to the media.
The Interior Ministry did not identify the suspect. The attacker's affiliation was not known and no militant group claimed responsibility for the bombings.
On Saturday, an attack on an Egyptian army checkpoint in the Sinai left 15 soldiers dead or wounded and seven of the suspected assailants killed, according to the military.
