The Arab League on Sunday accused Israel of carrying out "crimes against humanity" in the Gaza Strip after eight Palestinians were killed in a blast blamed on the Jewish state.
"The latest carnage is a yet another sign of Israel's immorality in the occupied Palestinian territories," League Secretary General Amr Moussa's spokesman said in a statement.
Israel "is committing crimes against humanity in Gaza," the 22-member pan-Arab body said.
Eight people, including senior Palestinian militant Ayman al-Fayed, his 37-year-old wife and three of their children aged 21, 19 and six, were killed in an explosion in Gaza on Friday for which Israel denied responsibility.
Three other people were also killed while 42 others, including 17 children, were wounded.
Palestinian groups have rejected Israel's denial of involvement in the blast, saying it was caused by an air strike.
Israeli troops on Sunday killed four Palestinians, including a civilian, in its latest assault on the Gaza Strip aimed at stopping rockets being launched at Israel.
More than184 people have been killed since peace talks were formally relaunched at a U.S. conference in November, the vast majority of them Gaza militants, according to an AFP tally.
