JERUSALEM, July 01, 2008, (WAFA)-Israel once again closed on Tuesday its cargo crossings with the Gaza Strip, accusing Palestinian militants of firing a rocket at southern Israel in violation of a shaky truce.

In recent months, Israel's passages with Gaza have been sealed to everything but humanitarian aid and fuel supplies. Israel had committed under the truce to allow in larger shipments of some supplies, but deliveries have not increased because of the attacks.

On Tuesday, Egypt again opened the Rafah crossing - Gaza's main gateway to the outside world - for two days to allow hundreds of people stranded on both sides to cross.

Palestinian diplomat Nabil Amr told reporters in Cairo on Monday that Palestinians needing medical treatment and those with residency permits in Egypt or other countries abroad would be allowed into Egypt.

Fifty Gazans with medical conditions were to be the first allowed out, traveling across the border in ambulances.
