Yemeni policemen and people gather at the scene where the bodyguard of Germany's ambassador to Yemen was killed on October 6, 2013.
Germany said Friday it was temporarily reducing its embassy staff in Yemen and told its aid workers to leave after an attack claimed by Al-Qaeda killed 52 people, including two Germans.
All German employees of government-funded aid and development organizations must leave Yemen "as quickly as possible", a foreign ministry spokesman told reporters.
The German embassy in the Yemeni capital will operate "in emergency mode with reduced personnel" and with appropriate security measures, he added.
Chancellor Angela Merkel is "extremely shocked" by the deaths of two German doctors in Thursday's attack on a Yemeni defense complex, government spokesman Steffen Seibert told a news conference.
She and the government "condemn the terrorist attack in the strongest terms", he said.
