The mayor of Libya’s third-largest city Misrata has been abducted and killed, a security source said on Monday.

Mohamad Eshtewi’s body was found dumped in the street after he was kidnapped by unknown assailants after leaving the airport in the western coastal city late Sunday, the source said.

The city hospital said it had received the mayor’s body bearing gunshot wounds.

His brother was with him in the car and was wounded in the attack, the security source said.

Eshtewi was returning from an official visit to Turkey with other members of the city council, who were all elected in 2014 for four years.

UN envoy for Libya Ghassan Salame on Twitter denounced the killing and expressed his "profound sadness" over the news.

Britain's ambassador to Libya, Peter Millett, said he was "deeply saddened by (the) senseless murder".

"He worked hard to serve his people," he said on Twitter.
