Paramedics rushed to the area to attend to the casualties after the blast, which ripped a hole through the building, Reuters reported.

At least three dead bodies were pulled out of the blast location while three wounded people were taken from the area, reports said. The exact casualty count was not yet known but Abdullah Mahmoud, a soldier, told Reuters that Yemeni and Iranian guards were among those killed. It was not clear if the diplomat was inside the well-guarded residence.

report from The Associated Press (AP) said that at least two people were killed and they were security guards of Iranian ambassador Hossein Niknam, who presented his credentials to the Yemeni Foreign Ministry just last week.

"The Sanaa explosion didn't harm any Iranian diplomats. Only material damage was inflicted," Iran's Deputy Foreign Minister Hossein Amir Abdollahian told Tasnim news agency, according to AP, adding that the ambassador was not hurt.
