Cyprus has dispatched 1,200 metric tons of humanitarian aid for Gaza by sea via Ashdod in Israel, its foreign ministry said on Tuesday.

Over 100 nonprofit groups have warned that Israel's rules for aid organizations in Gaza and the West Bank will block crucial relief efforts.

Israel’s public broadcaster KAN said the announcement comes “amid reports of discussions with South Sudan on the possible transfer of Gaza residents to its territory,” though Juba has denied any such agreement.

The American- and Israeli-backed Gaza Humanitarian Foundation has launched a new system to ensure greater civilian access to aid.

Israel has allowed more aid to flow into Gaza, under intense pressure over Palestinians starving to death, but the U.N. says much more is still needed.

Aid groups warn of deepening starvation as trucks have been unable to deliver vital supplies.

International aid was seen being airdropped in Gaza City on Sunday. For over two weeks different countries have been participating in the delivery of aid from planes.

Hamas said it was prepared to coordinate with the Red Cross to deliver aid to hostages it holds in Gaza, if Israel meets certain conditions.

The Prime Minister’s Office has authorized Indonesia to airdrop humanitarian aid into Gaza next week, despite the lack of diplomatic relations.
