The Israeli military has intercepted a Gaza-bound aid ship seeking to break the Israeli blockade of the Palestinian territory, detaining 21 international activists and journalists and seizing all cargo, including baby formula, food and medicine, the Freedom Flotilla Coalition said Sunday.

The coalition that operates the vessel Handala said the Israeli military “violently intercepted” the ship in international waters about 40 nautical miles from Gaza, cutting the cameras and communication, just before midnight Saturday.

“All cargo was non-military, civilian and intended for direct distribution to a population facing deliberate starvation and medical collapse under Israel’s illegal blockade,’’ the group said in a statement.
