The assailants first tried to kidnap the diplomat, but opened fire when faced resistance, according to Press TV.

In a statement, Iran foreign ministry strongly condemned the assassination of the Iranian diplomat as an "inhumane and terrorist" act targeting Muslim unity, said the report.

"The terrorist incident in the Yemeni capital of Sanaa... revealed the violent and extremist face of Takfiri groups, and is only in line with the wicked interests of the enemies of the Muslim world in targeting the unity and solidarity among the Islamic people," the statement said.

"The Islamic republic of Iran believes it is imperative that all countries, governments and international organizations take swift action to condemn such terrorist measures and adopt effective strategies to uproot this global problem," it added.

Iranian foreign ministry will use all its political and legal capacities to investigate the case along with the Yemeni officials for the immediate capture, trial and punishment of those behind the assassination, the statement stressed.
