The parents of an American man severely wounded by Israeli troops in a recent West Bank protest want the Israeli government to take responsibility for the incident.

Tristan Anderson was struck in the head March 13th by a tear gas canister fired by Israeli troops in the village of Naalin. Anderson is from Oakland, California.

Anderson's parents have come to Israel to see their son. In a news conference Monday in Jerusalem, Anderson's father, Mike, said he wants Israel to "publicly take full responsibility" for the incident.

Israeli officials had no immediate comment, saying the incident is under investigation.

Anderson was attending a protest against Israel's separation barrier which threatens to take hundreds of acres of Naalin land.
