An elderly Palestinian man died Thursday morning, a day after breathing in the fumes from a tear gas canister fired by IDF soldiers that landed in his home.

The tear gas was fired by the military during a demonstration in the village of Kafr Qaddum, near Nablus, on Wednesday.

It was meant to disperse protesters, but local Palestinians told Reuters Thursday that it hit the elderly man’s village home, exposing him to hazardous fumes.

The man, 85-year-old Saeed Jaser Ali, died in a local hospital hours later.

The northern West Bank villager is the first casualty of the Israeli-Palestinian conflict in 2014.

The incident began when a violent confrontation between IDF troops and Palestinian protesters erupted during a celebration in the village of the 49th anniversary of the founding of the Fatah movement.

The troops used riot control methods to disperse the protesters, including gas canisters, Palestinians said.

An IDF spokeswoman said she was looking into the details of the incident, which occurred as US Secretary of State John Kerry was making his way to the region for yet another round of peace talks between Israel and the Palestinian Authority.

On Tuesday, Israeli human rights NGO B’Tselem announced that 27 Palestinians were killed by the Israeli military in the West Bank in 2013, more than triple the number killed in the previous year.

The organization’s annual report also found that for the first time in 10 years, more Palestinians were killed in the West Bank than in the Gaza Strip.

The study reported 21 fatal incidents in the West Bank during 2013, versus seven altercations in Gaza that left nine Palestinians dead.

In 2012, Israeli security forces killed eight Palestinians in the West Bank and 246 in Gaza, 167 of them during Operation Pillar of Defense. According to B’Tselem, 104 of the 246 were noncombatants.
