Immigration authorities on Wednesday deported 15 international activists who were arrested after their ship, the Estelle, attempted to break Israel's naval blockade of Gaza.

The pro-Palestinian activists were sent back to their homelands, with two more scheduled to be deported late Wednesday night. Ten other activists were deported on Sunday and Monday. Three of the activists are Israeli and were released on bail.

Parliament members from Norway, Sweden, Spain and Greece were among the activists, as well as former Canadian lawmaker Jim Manly.

IDF naval commandos on Oct. 20 boarded the Estelle, a Swedish-owned, Finnish-flagged sailing vessel, as it approached Gazan territorial waters. The IDF spokesman said in a statement that the commandos did not use force, while the activists allege that the commandos unnecessarily used Taser guns to subdue them.

Israel imposed the blockade on Gaza in 2007 after the terrorist group Hamas took control of the coastal strip. It says the sanctions are to prevent weapons and other terror material from being smuggled in to Gaza.

The Freedom Flotilla's first attempt to break the blockade ended in the deaths of nine Turkish activists after Israeli Navy commandos on May 31, 2010 boarded the Mavi Marmara, which claimed to be carrying humanitarian aid, after warning the ship not to sail into waters near the Gaza Strip in circumvention of the maritime blockade.
