The fragile truce between Israel and Palesinian groups, that begun 9 days ago in the Gaza Strip, appears to have been violated repeatedly by both sides.
Causing injuries, Israeli troops have opened fire on Palestinian farmers several times, says a UN source. But Israel says its forces fired warning shots.
The ceasefire has also been broken by Palestinian militants, who have fired rockets and mortars into Israel territory.
In the same time, the Gaza border has been kept closed by Israel for a third day.
Fuel has been allowed into the Gaza Strip by the authorities, who have blocked all other supplies, including humanitarian and commercial goods.
But BBC’s correspondents say that, despite the breaches, the ceasefire is officially holding.
Ceasefire under strain
The main Palestinian group in Gaza, Hamas, says it is still committed to the truce.
But it is other Palestinian groups that are firing the rockets and mortar : Islamic Jihad and the al-Aqsa Martyrs Brigades. The latter is affiliated to the Fatah, faction of Palestinian Authority President Mahmoud Abbas.
It is not clear how much control Hamas has over these other groups, says the BBC’s Wyre Davis, in Jerusalem. He adds that the ceasefire is put under strain by gunfire from the Israelis and continued rocket fire from the Palestinian side.
Two mortar rounds landed in an open field on the Israeli side of the border on Friday, reported Israel Radio.
And before Friday, Palestinian militants had fired four rockets into Israel, since the truce was agreed, on 19 June.
They are a response to Israeli violations of the truce, say the militants.
Border crossings has been kept closed by Israel for a third consecutive day, in response to the rocket attacks.
A European Union Official told the Reuters news agency that an estimated 600,000 litres of industrial fuel will be allowed to pass through the Nahal Oz border terminal for Gaza’s only power station. It will keep the plant running for several days.
The deliveries of fuel to the power station are funded by the EU.
The fuel delivery has been confirmed by Israeli officials, who said other border crossings remained closed.
Though Gaza’s Hamas rulers have called on all groups to respect the ceasefire, they say they will not be Israel’s “police”.
And Israel says that the crossings into Gaza will remain closed until rocket attacks stop.
