Residents of Yemen’s capital, Sana, shared vivid accounts of life during wartime on social networks on Monday, as a huge blast shattered windows and shook buildings miles from the site of an attack in the Faj Attan district of the city.

Dozens of people were feared dead after the airstrike by a Saudi-led military coalition set off a huge explosion that flattened homes in the neighborhood, witnesses said.

Strikingly clear images of the blast were captured in a video clip widely shared from phone to phone using the WhatsApp messaging service. The latter portion of that clip also gave a sense of the powerful shock wave that shattered glass around the capital.
