LONDON, March 3. /TASS/. A fire erupted at the US Embassy in the Saudi Arabian capital of Riyadh following an explosion, Reuters news agency reported on Tuesday.

AFP news agency reported earlier citing eyewitnesses that two powerful explosions went off at the US diplomatic mission in Riyadh.

The Defense Ministry of Saudi Arabia reported that the US Embassy in Riyadh came under attack delivered by two Iranian unmanned aerial vehicles (UAVs). According to the ministry, the facility of the diplomatic mission sustained minor damage and the scale of the reported blaze was insignificant.
