DHAKA: The US is prepared to broker a ceasefire between Israel and Palestinian militants in Gaza, President Barack Obama has said.

His comments came during a phone conversation with Israeli Prime Minister Benjamin Netanyahu.

Netanyahu earlier said Israel's operation was progressing as planned and "more stages were expected".

More than 90 Gazans have been killed since Israel's campaign began on Tuesday, Palestinian officials say.

About 600 have been injured, most of them civilians, according to the Palestinian health ministry.

Israel says it hit more than 100 targets in Gaza on Thursday, while Palestinian militants have continued to fire rockets into Israel.

There have been no reports of fatalities in Israel.

At least one rocket was fired from southern Lebanon into northern Israel early on Friday, but no casualties have been reported.

"One projectile hit an open space near Kfar Yuval, between Metula and Kiryat Shmona," a military spokeswoman told the AFP news agency.

Israel launched its operation Protective Edge after a surge in rocket fire from Gaza amid a crackdown on Hamas members in the West Bank last month, as Israel hunted for the abductors of three Israeli teenagers, reports BBC.

The teenagers were found murdered, and tensions were raised further with the killing of a Palestinian teenager in a suspected revenge attack days later.
