EU's Foreign Affairs High Representative Catherine Ashton has condemned the recent attempt to kidnap Bulgaria's Ambassador to Yemen, Boris Borisov.

Ashton, "condemns the attack in Sanaa on May 12 that injured the Bulgarian Ambassador to Yemen, Boris Genadiev Borisov, and expresses the sincere solidarity of the European Union," a statement has said.

"The High Representative calls on the Yemeni authorities to take the necessary measures to ensure the protection of foreign nationals and diplomats and do the utmost to investigate the incident," she added, pointing out that the incident shows the fragile security situation in the country.

On Saturday,  Boris Borisov was slightly injured after masked gunmen opened fire at his vehicle in an attempt to kidnap him.

Bulgaria's Foreign Ministry has already condemned the incident.

"We expect the Yemeni authorities to take urgent steps to identify the perpetrators of this outrage, and to prevent the occurrence of such incidents in future. The political and tribal divisions in Yemen should be resolved through political dialogue and not through violence," Bulgarian Foreign Minister Nikolay Mladenov declared in a statement on Sunday.
