Israel air strikes resume in Gaza amid rockets
The Israeli army called the renewed rocket attacks "unacceptable, intolerable and short-sighted".
Palestinian militant group Hamas, which controls Gaza, earlier rejected any extension of the truce, saying Israel had failed to meet its demands, BBC News reports.
Some 1,940 people have died in four weeks of fighting in Gaza.
Palestinian officials say at least 1,875 people have been killed since Israel launched Operation Protective Edge on 8 July with the stated aim of halting rocket fire from militants in Gaza and destroying the network of tunnels it said were used by militants to launch attacks inside Israel.
The UN says 1,354 of those who died were civilians, including 415 children and 214 women.
Israel's government says 64 soldiers were killed, along with two Israeli civilians and a Thai national. It also claims that about 900 Palestinian militants were killed in the fighting.
