JERUSALEM — Pro-Palestinian groups say hundreds of activists from around the world intend to fly to Israel's airport on Friday to protest the country's naval blockade of the Gaza Strip and other policies.

By staging large demonstrations at the airport, Israeli media say the activists plan on disrupting flights. Media reported that already tight security at the airport will be beefed up. Police refused to comment on operational preparations.

The groups that called Sunday for the protest are based in Europe and the U.S. They include the International Solidarity Movement, a pro-Palestinian group that often sends activists to the West Bank and Gaza.

The planned protests come amid stalled efforts by a flotilla of activists to reach Gaza by sea.
