A Yemeni diplomat, Rasheed Mohammad Al-Qadasi, was killed in the Syrian capital, Damascus, a Yemeni newspaper, Al-Shara'a said.
It quoted sources of Al-Qadasi's family as saying that armed group attacked him in his home as they were attempting to steal his car.
No Yemeni official sources affirmed the killing of Al-Qadasi so far.
The killing incident comes among criticisms against the Yemeni Embassy to Syria, emphasizing that it badly deals with Yemenis residing in Syria, particularly students, according to Al-Tagheer news website.
President Abdu Rabo Mansour Hadi had directed the Yemeni authorities to facilitate the travel of Yemenis residing in Syrian and granting visas to those planning to leave the state, but Yemenis accused the embassy of blackmailing them.
Two Yemeni students who were arrested for several months by the Syrian security authorities accused the embassy of doing nothing toward their case and that it misled the Yemeni public opinion about them.
The Syrian Free Army has said that it arrested fighters of the Yemeni Shiite Houthi group fighting with the Syrian regime.
a spokesman of the Syrian National Coalition, Wael Hafiz, said the Houthi group urged the Houthi group to stop sending its fighters to Syria.
Meanwhile, Yemeni protesters repeatedly demanded the authorities to expel the Syrian Ambassador to Yemen after the escalation of violence against the Syrian people by the regime.
They condemned "massacres" committed by the Syrian regime against the Syrian people, demanding the Yemeni government to immediately expel the Syrian Ambassador.
