Mr. Speaker. in response to the massacre of more than 1.000 defenseless Palestinians in the refugee camps at Sabra and Shatila. on the outskirts of Beirut. President Reagan ordered U.S. troops to return to Beirut. with French and Italian peacekeeping soldiers. to encourage the Israeli Army to withdraw. According to generally accepted reports. Israelis invaded the west section of this capital city of Lebanon. contrary to its agreement which secured the withdrawal of PLO forces. and with cabinet approval permitted Israeli equipped and trained "Lebanese militiamen" to travel the some 35 miles from the LebaneseIsraeli border and enter the camps with knowledge of their intent for a murderous rampage which lasted more than 36 hours.
