What we know about the Hungary-based company facing questions over pager attacks in Lebanon

Relatives mourn 10-year-old Fatima Abdallah, who was killed after hundreds of paging devices exploded in a deadly wave across Lebanon. At least 37 people died, and more than 2,900 others were wounded as pagers and walkie-talkies used by Hezbollah exploded in the unprecedented attacks. The blasts, spanning two days, have dealt a major blow to the Iran-backed militant group, which blamed its arch-foe Israel for the attacks on its communication systems and vowed revenge.
