“Rescue workers in Beirut are delicately exploring the rubble of a collapsed building where a specialist team says it detected signs of life — one month after Lebanon’s capital was devastated by a massive explosion at its port. The effort began after a sniffer dog named Flash signaled to his Chilean search and rescue team that someone might be alive under the concrete and debris in the neighborhood of Mar Mikhael. Searchers said their sensors have confirmed the presence of a body — initially detecting a possible breathing cycle on Thursday and then what they believe could be a weak human pulse.” A small chance at a miracle in a city that could really use one.
