Two young men allegedly drowned early Saturday in one of Yerevan’s reservoirs after one attempted to rescue the other, authorities said.

Armenia’s Ministry of Internal Affairs said its 112 Operational Management Center received an emergency call at 5:49 a.m. reporting that an individual had allegedly fallen into a reservoir and his friend had jumped in to help.

Emergency response teams were dispatched to the scene, including units from the Rescue Service, a firefighting crew from the Yerevan department, a specialized water rescue team and police.

Officials said a diver later located and recovered the bodies of the two victims from the water.

Other details were not immediately available.
