Israeli soldiers reportedly killed one man and wounded another 19 near the fence which separates Gaza from Israel.
Troops opened fire in Khan Younis on Friday after "several rioters damaged the fence and attempted to cross into Israel's territory," the IDF spokesperson told Israel’s Army Radio.
"IDF forces made efforts to disperse the rioters, and when they refused to leave warning shots were fired," the army said.
According to the IDF, troops fired at the legs of the rioters who attempted to cross the border. One man who managed to enter Israel was detained and later returned to Gaza, according to the news site Ynet.
The Palestinian news agency Ma'an, which cited witnesses and medical officials in Gaza, reported the dead Palestinian was 21 years old and that another 18 were injured. A relative of the man told Reurters that the 21-year-old tried to hang a Hamas flag on the fence. An IDF soldier fired three times in the air and finally the man was shot in the head.
A top Islamic Jihad official, Nafez Azzam, condemned the incident and said it constituted a breach of the truce as well, the news agency said.
In the West Bank, IDF forces reportedly arrested a few dozen Hamas supporters, according to Army Radio. Four of those arrested are Palestinian parliamentarians, including the Parliament secretary general, Mahmoud al-Ramhi.
