Zarif had telephonic conversations with his counterparts from Algeria, Jordan, Pakistan, Sudan and Morocco Sunday, Press TV reported.
Efforts must be intensified to provide Gazans with humanitarian aid as well as medical supplies and treat those wounded in Israeli raids, he said.

Zarif: Efforts must be made to provide humanitarian aid to the wounded
On Sunday, Hamas spokesman Sami Abu Zuhri said in an emailed press statement that Hamas and the Palestinian factions agreed to accept the UN-proposed ceasefire for 24 hours, but Israel rejected it.
A Palestinian was killed and 10 injured Sunday after Israeli war jets resumed airstrikes on Gaza, where a UN-proposed humanitarian ceasefire for 42 hours between Israel and Hamas collapsed.
On July 8, Israel launched a large-scale operation on the Gaza Strip, where 1,030 Palestinians and 43 Israelis have been killed and more than 6,000 Palestinians injured.
