GAZA, April 9 (Xinhua) -- Hamas said on Tuesday that Israel's closure of the Gaza Strip's crossings has a negative effect on the Egyptian-brokered ceasefire between the two sides in November 2012.
The repeated closures of Gaza commercial crossing "is a consolidation to the principle of the collective punishment on the Palestinians," Ziad Zaza, the deputy premier of Hamas government, told Xinhua.
Israel announced on Monday that it decided to close the two main crossings between Israel and the Gaza Strip following a barrage of rockets fired into its southern territories by unknown militants.
"The Israeli measures are endangering the ceasefire understanding reached in November and this would certainly drag the area to more tension and to uncontrolled situation, and Israel will be held fully responsible," said Zaza.
Israel had closed the crossings of the Gaza Strip for 13 days during March, said Zaza, who is also the minister of national economy in the Hamas-run government.
"This is a clear violation of the ceasefire deal," he stressed, reiterating that the repeated closure of the crossings is not only leading to tension and to an uncontrollable situation, but also lead to great losses to the weak Palestinian economy.
Zaza called on the Egyptian authorities to immediately intervene to end the closure.
Egypt brokered a ceasefire agreement between Hamas and Israel last year. Under the agreement, Hamas militants in Gaza are to refrain from launching rockets on Israel, and Israel, in turn, is to stop its air strikes and ease the blockade it imposed on the territory after Hamas seized control of it in June 2007.
