The air-traffic control in Sana'a ordered the pilot of the twin- engine Cessna 421 to land in Sana'a for lacking a clearance from air- defence authorities to fly over Yemeni airspace, the officials said.
"The plane was grounded in Sana'a this evening after it was found overflying Yemeni airspace without prior permission," one official, who wanted not to be identified, told Deutsche Presse-Agentur dpa.
Only the pilot and a passenger were on board, he said, adding that security officials were investigating the incident.
The aircraft took off from Jeddah, Saudi Arabia. The plane's intended destination was not immediately known, dpa reported.
