Gush Shalom slammed the Israeli Navy's decision to board the Gaza-bound "Estelle" on Saturday morning and reroute the ship, labelling the incident evidence of expansion of the occupation into international waters.

In a statement released shortly after the incident, the NGO called the incident "brutal" and "senseless."

The organization confirmed that three Israeli activists were onboard the Swedish ship - Alec El-Hanan, Reut Moore and Jonathan Shapira.
