Israel unleashed a wave of deadly airstrikes on Yemen's capital on Sunday, with footage capturing a colossal fireball erupting near the presidential palace.

At least six people were killed and 86 wounded, according to the Houthi-run health ministry, with seven said to be fighting for their lives.

The strikes shook Sanaa overnight, hitting multiple sites including an oil facility, a major powerplant, and a military compound near the presidential palace.

Social media footage captured a huge orange fireball rising from the Asar oil facility, while residents reported terrifying blasts that shattered windows and sent smoke billowing across the city.

Blazing flames formed a thick column up into the sky as a black mushroom cloud topped the blast. Onlookers were seen yelling in terror and running for their lives.
