Israel has said it will intensify its artillery bombardment of the Gaza Strip to deter rocket attacks by Palestinian militants on its territory.

Officials said they regretted the recent deaths of a number of Palestinian civilians but were set on stopping the rocket attacks.
An eight-year-old girl killed by a shell on Monday has been buried.
She was the 16th Palestinian to die in Israeli air and artillery attacks on Gaza in the past four days.
For months, the Israeli army has been firing artillery rounds into open areas of northern Gaza in an effort to strike at, or deter, militants.
Israeli Defence Minister Shaul Mofaz said the shelling was in direct response to militant attacks.
"As long as calm does not prevail on the Israeli side, neither will it do so on the Palestinian side," he said. "Our operations are going to intensify."
The Palestinians' new Hamas prime minister, Ismail Haniya, accused Israel of trying to bring the Palestinian people "to their knees" and "strangling" his government.
People gathered in a clearing next to an olive grove on Tuesday to mourn the latest civilian victim of the shelling, eight-year-old Hadil Ghraben.

She was watching television in her house in the northern village of Beit Lahiya when an Israeli shell came crashing through the roof, killing her instantly.
Seven of her brothers and sisters were hurt.
The Israelis admit there was no militant rocket fire from the area at the time but they say there had been earlier, and that they had been trying to deter more.
An army officer telephoned to apologise to Hadil's father, Mohammed, but he was unimpressed.
"I told him 'you didn't hit the people who fired the rockets, you hit the little kids and civilians'," Mohammed told the BBC.
" 'What did those kids do? They were at home, inside. And now you call to apologise'."
There was a chaotic scene as Hadil's body arrived from the hospital to be borne through the crowd of grieving relatives.
A woman among the mourners delivered a message for the Israelis: "We will cut you to pieces, I swear it, just as you have done to us."
The BBC's Alan Johnston, who was at the funeral, said militants with guns, from organisations like Islamic Jihad, were moving among the mourners.
It is groups like these that are firing rockets into Israel, saying they are responding to Israel's escalation of the violence and the killing of militants in recent days, our correspondent says.
For its part, Israel says it is determined to stamp out the rocket fire and it is using its big guns more and more aggressively, he adds.
