UN Secretary-general Ban Ki-moon condemned on Monday the "terrorist attack" that killed Kamal Medhat, deputy head of the Palestine Liberation Organization (PLO) in Lebanon, and several of his bodyguards, Xinhua reported.
"He (Ban) conveys his condolences to the families of the victims. He hopes that the perpetrators of this crime will be brought to justice promptly," Ban's press office said in a statement.
"Such actions must not be allowed to endanger the climate of calm that currently prevails in Lebanon," the secretary-general said.
Kamal Medhat and at least two bodyguards were killed on Monday by a roadside bomb near the entrance of Miyeh Miyeh Palestinian refugee camp in south Lebanon, according to media reports.
