By Nidal al-Mughrabi and Allyn Fisher-Ilan GAZA/JERUSALEM (Reuters) - Hamas-led gunmen in Gaza executed 18 Palestinians accused of collaborating with Israel on Friday, accelerating a crackdown on suspected informers after Israeli forces tracked down and killed three senior Hamas commanders. Israeli Prime Minister Benjamin Netanyahu threatened to escalate the fight against Hamas, vowing the group would "pay a heavy price" after a four-year-old Israeli boy was killed by a mortar attack from Gaza, the first Israeli child to die in the six-week conflict. Shortly after his remarks, Palestinian officials said Israel had flattened a house in a Gaza City air strike, wounding at least 40 people. Israel's military spokesman said another ground war was possible if necessary to stop the rocket fire.
