A gun battle has taken place between Afghan security forces and militants in the eastern city of Jalalabad, according to a government official cited by Reuters. At least three explosions were heard at the beginning of what authorities believe to be a coordinated attack, Nangarhar provincial governor spokesman Attahullah Khogyani said. The battle took place inside a building which houses the state accounts office. No one has claimed responsibility for the attack. However, the Taliban is currently taking part in its annual spring offensive and has launched a number of attacks in recent weeks.
