GAZA (Reuters) - The Palestinian death toll from Israeli live fire in protests along the Gaza-Israel border on Monday rose to 52, a Palestinian health ministry official said.

It was the highest toll in a single day since a series of such protests demanding the right to return to ancestral homes in Israel began on March 30.

Palestinian Health Ministry spokesman Ashraf Al-Qidra said the dead included six children under the age of 18. About 2,400 Palestinians had been wounded, about half of them by live bullets.
