A large explosion rocked Afghanistan's capital Kabul on Friday evening, police said.

Officials said the attackers reportedly targeted the Spanish embassy and have entered a building near the compound.

"Kabul police are at the site of the explosion," Sediq Sediqqi, spokesman for the Afghan Interior Ministry, said. "We are gathering details as they emerge."

Emergency Hospital, an Italian-run medical facility located less than a kilometer from the blast site, said on Twitter that it has received seven injured people following the attack.

Afghan VP Abdul Rashid Dostum and other high-level government officials live in the area.

Earlier this week, Taliban militants killed at least 50 civilians and security personnel in a coordinated attack on Kandahar airfield.
