The Egyptian Foreign Ministry is protesting demonstrations held in Syria over Egypt's role in the blockade of the Gaza Strip.
The state-owned Middle East News Agency said Deputy Foreign Minister Abdel-Rahman Salah expressed concern about the demonstrations to the Syrian ambassador after summoning him to the ministry Tuesday.
The agency quoted Salah as describing the protesters as mobs.
Thousands of protesters, mostly Palestinian refugees, took part in demonstrations this week in Damascus demanding the closure be reversed.
Israel and Egypt imposed a blockade on Gaza after Hamas seized power last year, ousting the forces of Palestinian Authority President Mahmoud Abbas.
