"The blast took place in front of the Ziba Hotel in Jalalabad city, where a university lecturer was killed and three other lecturers were injured", he said.
No militant group has claimed responsibility for the bombings but both the Taliban and a Central Asian branch of the Daesh* terrorist group are active in large parts of Nangarhar province that shares a long border with Pakistan.
The report comes after a Pakistan's Foreign Ministry spokesman stated that three people were injured on 25 August as a result of a bomb blast outside the Pakistani Consulate General in Afghanistan's Jalalabad.
Before that, Afghan Chief Executive Abdullah Abdullah, who is also a presidential candidate, stated that more than 100 people are being killed in the years-long conflict every day.
For almost two decades, Afghanistan has suffered instability due to the continuous insurgency of the terrorist groups. Government forces conduct regular counterterrorism operations across the country.
*Daesh (also known as ISIS/ISIL/IS) is a terrorist group banned in Russia
