The Popular Resistance Committees (PRC), a militant group, Thursday announced rocket attacks against Israel lasting until the end of the Muslim holy month of Ramadan, which began today.

In a press statement, the PRC said its campaign, called "The Messages of Death," will include rocket attacks on Israeli cities and military bases alongside the Gaza Strip.

As part of the campaign, the PRC said it had targeted an Israeli army base in eastern Gaza with four mortar shells. The brigades also fired three homemade rockets into Sderot, Ashkelon and Zikim towns in southern Israel.

"The operation is a response to the Israeli crimes against our people in the Gaza Strip and the West Bank and to affirm the continuation of resistance," the statement said.

PRC's statement came amid intensified rocket attacks against Israel by Gaza-based militants.

On Tuesday, a Palestinian homemade rocket slammed into an Israeli army training camp in southern Israel, wounding 69 Israeli conscripts.

Following the attack, some Israeli officials called for tough retaliation against militant groups' rocket attacks launched from the Gaza enclave.
