”Israeli” occupation forces have been shelling Gaza for a fifth day, killing at least 12 Palestinians, according to agencies.
Four children were among the dead in Gaza. Two media buildings were also hit, injuring Palestinian journalists.
However, UK Foreign Secretary William Hague warned that a ground invasion would “lose “Israel” a lot of the international support”.
The occupying power confirmed to the BBC that it knew foreign journalists were in at least one of the two media buildings it struck in Gaza.
One of the eight injured Palestinian journalists had to have a leg amputated.
The Middle East Foreign Press Association has issued a statement expressing concern at the air strikes on the media buildings.
Among those using the buildings were al-Quds TV, as well as Sky News and ITN. The BBC had its offices in one of the buildings until last year.
The Russian TV network Russia Today said its office in one of the buildings was damaged.
Health officials in Gaza say at least 58 Palestinians have now been killed since Israeli occupation troops their aggressive operation on Gaza on Wednesday.
The officials said a number of people were still missing under rubble and the total of injured since Wednesday was now 560.
The World Health Organization says hospitals in Gaza are overwhelmed with casualties and short on supplies.
