How many Hamas militants have been killed in the fire? [br] [originaltext]

In the Gaza Strip today, an Israeli airforce plane fired missiles at three Hamas militants who Israel said had fired mortars. An Israeli army spokesman said the men escaped unharmed although their car was destroyed.
     An Israeli army spokesman said the three men had fired a mortar shot from hand units in southern Gaza in the direction of Jewish settlements in Gaza and were preparing to launch more. Military sources said the strike was not an Israeli assassination attempt, but an assault on a gunman as they were firing. Yesterday three workers, one Chinese and two Palestinians, were killed, when Palestinians fired mortars at a Jewish settlement in Gaza. Palestinian leader Muhammadan Abbas travelled to Gaza today for a talk with Hamas. Abbas urged Israel to stop what he called" illogical acts", like the missile strikes, which he said could cause the current ceasefire to collapse. Israel says Abbas must do more to stop their rocket and mortar fire.
