Gaza's Hamas leaders renewed on Friday its commitment to mutual truce with Israel whose air strikes has surged over the past week.
A 22-day Israeli military offensive, which ended in January 2009, killed up to 1500 Palestinians, devastating Gaza's infrastructure and homes to rubble.
Israeli warplanes recently staged a series of air attack into Gaza, causing deaths and Palestinian fighters fired mortar shells into southern Israel, usually leading no casualties.
(One Palestinian was killed and three were wounded in the northern Gaza Strip on Thursday.)
In front of a crowd of supporters in southern Gaza after Friday prayers, senior leader Mahmoud Al-Zahar said Hamas would be committed to a ceasefire if Israel abided by it.
Zahar said Hamas and other factions were committed to an agreement they had reached last year to stop rocket firing into Israel, although smaller groups continued to launch attacks.
"We are committed to self-restraint as long as there is no oppression and no aggression," said Zahar.
Hamas has said in the past it would agree to a long-term truce.
