A flotilla of human rights activists on their way to deliver aid to the Gaza strip have been intercepted by the Israeli navy.
A Turkish television channel reported that Israeli troops fired at the international convoy early on Monday morning, killing two aid activists and wounding at least 30 more.
The flotilla included a Turkish ferry carrying 600 people and was organised by pro-Palestinian groups and a Turkish human rights organisation.
Israel had warned the convoy that it would be stopped if it tried to reach Gaza by sea, despite a request by Turkey to give the ships safe passage.
Israel set up a holding camp for the activists at the coastal city of Ashdod. Activists risk arrest and detention.
