At least one person was killed and 17 wounded Wednesday when a car bomb struck the residence of Iran's ambassador in Yemen, where Tehran is accused of backing Shiite militia.
Ambassador Hassan Sayed Nam was not at home when the attack took place in the diplomatic district of Hada in the capital Sanaa, according to a security official.
The son of a guard at the residence was killed, according to an interior ministry statement given by the official Saba news agency.
A security official had earlier said it was a guard who died.
Two of the 17 wounded were guards and the rest passers-by, officials said.
The blast left a hole in the outer wall of the house. Nearby homes and cars were also damaged.
The identity of the attackers was unclear and the interior ministry said it had launched an investigation into the attack.
Shiite Huthi militiamen who have overrun the capital quickly cordoned off the area, which is near the intelligence headquarters in Sanaa, according to residents.
It was not the first attack targeting Iran in Yemen.
