Missiles fired from Israeli warplanes overnight Sunday struck a Hamas naval building in northern Gaza, killing 1 person and injuring at least three others, according to Hamas security and medical officials.
Two rockets struck the building, north of Gaza City, according to a Hamas security official.
That official claimed one person had died and five were hurt. Adham Abu Salima -- a Hamas medical official -- confirmed the one fatality and added there were at least three injuries.
Into early Monday, Hamas troops were believed to be buried under the rubble, Salima said. Officials were calling for help to rescue them by clearing the debris, Salima said.
Israel Defense Forces said in a statement released early Monday that its aircraft had scored "a direct hit" on what it called "a terror activity site in the northern Gaza Strip."
"The targeting of this site was in response to the firing of a rocket at Israel on Sunday evening," the Israeli military said.
"The IDF will not tolerate any attempt to harm the state of Israel and IDF soldiers, and will continue to operate against anyone who uses terror against the state of Israel." the IDF statement said. "The Hamas terror organization is solely responsible for any terrorist activity emanating from the Gaza Strip." more
