Israel says extra police troops will be deployed at the country's international airport ahead of arrival later this week of pro-Palestinian activists protesting the naval blockade of the Gaza Strip.

Police spokesman Micky Rosenfeld says the beefed-up contingent of hundreds of officers will be ready to act in case of disruptions.

Prime Minister Benjamin Netanyahu met with senior security officials at the Ben-Gurion International Airport on Wednesday to review the procedures.

Netanyahu says "every country has a right to block the entry of provocateurs."

Hundreds of activists from around the world are expected to fly in Friday after efforts to send a flotilla of ships to bust the blockade have stalled.

Activists say they plan no disruptions.
