Israel-Gaza conflict escalates as death toll rises

Israel’s military says it is ready to launch an offensive in the Gaza Strip after four Israeli civilians were killed by rockets.

It has sent tanks and more than 1,000 extra soldiers to the border and told them to prepare to attack.

21 Palestinians have been killed in the fighting, which is the worst between Israel and Gaza in years.
