Signal in Beirut rubble raises hope for survivor a month after explosion

A pulsing signal has been detected from under the rubble of a Beirut building that collapsed during the explosion in the Lebanese capital last month, raising hopes there may still be a survivor buried there.
The effort unfolded after the sniffer dog belonging to the Chilean search and rescue team first detected something as the team was going through Gemmayzeh Street in Beirut and rushed towards the rubble of a building. The street was one of the hardest-hit in the explosion on August 4.
