UN: 178 killed in Beirut explosion, 30 still missing

The death toll from last week's massive explosion in Lebanon's capital has risen to nearly 180, with an estimated 6,000 people injured and at least 30 missing, the United Nations said Friday. The explosion has affected operations at six hospitals, up from an initial three, and damaged more than 20 clinics in the parts of Beirut worst hit by the blast, the U.N.'s humanitarian affairs agency said in its report. It still wasn't known what caused the Aug. 4 fire that ignited nearly 3,000 tons of ammonium nitrate stored in Beirut’s port.
