An Israeli shell on Saturday wounded three Palestinian militants who were firing rockets into Israel in northern Gaza Strip, Palestinian medical sources and witnesses said.
"The three fighters were moderately injured by shrapnel of an artillery shell," said Mu'awia Hassanien, a Palestinian emergency official.
Witnesses said the fighters were launching the rockets from the west of Beit Lahiya town, an agricultural community located on the border with Israel in northern Gaza Strip. The witnesses added the rocket cell belonged to Islamic Hamas movement which controls the Gaza Strip.
Meanwhile, Israeli sources said that a rocket, fired from Gaza, landed in Western Negev, causing damages to a building.
The Popular Resistance Committees (PRC), an armed group loyal to Hamas, claimed responsibility for the rocket-fire, saying it was part of a new operation that includes continues firing of mortars and rockets into Israeli border towns.
On Friday, two Palestinian girls were killed when a Palestinian rocket mistakenly hit their house in northern Gaza Strip.
An Egyptian-brokered ceasefire between the Palestinian militant groups, led by Hamas, and Israel collapsed in early November, nearly 45 days earlier than the scheduled date of Dec. 19.
Since then, the armed groups heavily resumed rocket attacks into Israeli communities near Gaza and Israel kept responding by increasing air and ground raids into Gaza. Hamas accused Israel of first violating the agreement by launching an incursion into Gaza, killing six militants.
Israel also restored restrictions to cargo flow to the Hamas- controlled territory, reported Xinhua.
