MOSCOW, July 1 (RIA Novosti) - Russia's emergencies ministry has delivered to Jordan three batches of humanitarian assistance destined for the Palestinians territories, the Foreign Ministry said in a statement Tuesday.

Israel once again closed Gaza border crossings earlier Tuesday in response to a Palestinian mortar attack on southern Israel late Monday. All but one of the Gaza border crossings are shut, halting supplies of food and other essential items to the Palestinian enclave.

"Three Russian emergencies ministry planes delivered on July 1 a large humanitarian cargo of food, medicine and tents to the Jordanian capital, Amman. The Russian assistance is designated for the population of Palestinian territories, including the Gaza Strip, where the humanitarian situation remains difficult," the statement reads.

Two Russian planes delivered 30 metric tons of food and medicine each on June 24 and 28 at the request of the Palestinian government.
