The United States has condemned Hamas's breach of the ceasefire Tuesday, blaming the Islamist terror group for the breakdown of talks over a long-term truce in Cairo.
"Hamas has security responsibility for Gaza... Rocket fire came from Gaza," State Department spokeswoman Marie Harf said, blaming the Palestinian Islamist group for renewed fighting.
Despite the blatant breach of the ceasefire by Gaza rocket-fire, Hamas has blamed Israel for the breakdown in talks.
A senior Hamas official said Tuesday the chances of a durable ceasefire in Gaza were "evaporating" and that there had been no progress in indirect negotiations with Israel.
The official, Ezzat al-Rishq, is among a Palestinian delegation in Cairo where Egyptian mediators are racing to bridge the gaps ahead of the expiration of a temporary ceasefire at midnight.
"There is no progress in the negotiations. Chances of an agreement are evaporating, and we hold the Zionist occupation fully responsible for that," Rishq wrote on Twitter.
He said the Palestinian delegation had presented the Egyptian mediators with their final position, which was relayed to the Israelis.
The Israeli team "left with the excuse of presenting it to their cabinet," Rishq wrote.
Israel ordered its delegation to leave Cairo and renewed air strikes on Gaza after a salvo of rockets hit the south of the country, hours before the truce was to expire.
At least eight rockets and mortar shells have been fired on Israel by Gazan terrorists on Tuesday, starting with three rockets aimed at the southern city of Be'er Sheva shortly before 4 p.m.
