A night of Israeli air raids and Palestinian rocket attacks left dead and wounded civilians on both sides of the border, as tensions escalated following an Israeli covert operation in Gaza that resulted in the deaths of an Israeli lieutenant colonel and seven Palestinian fighters.
At least seven Palestinians, among them five militants, have been killed during the fighting.
The air raid was part of the fresh airstrikes and rocket attacks by Israeli warplanes and artillery which are targeting areas "throughout" the Gaza Strip and have so far killed several people, including a Hamas commander.
Israeli strikes on Gaza have increased this year leaving behind many civilian casualties. On Sunday, Israeli Prime Minister Benjamin Netanyahu said he hoped to reach an "arrangement" that would avoid another conflict and ease Israeli-blockaded Gaza's economic hardships.
Later on Tuesday, Palestinian militant groups in Gaza, including Hamas, said they would halt cross-border attacks immediately if Israel did the same.
The building for Hamas's Al-Aqsa TV was destroyed in an Israeli strike after a series of warning shots, with the Israeli army saying the station "contributes to Hamas's military actions".
Lieut-Col. Jonathan Conricus, an Israeli military spokesman, said Hamas and the Islamic Jihad group have more than 20,000 rockets and mortars.
Two were killed in a strike targeting a group near Aisha mosque east of Rafah, after Israel said it was targeting individuals that were members of "terror squad" launching rockets.
The headquarters of Al-Aqsa TV station run by the Palestinian resistance movement Hamas was razed to the ground on Monday in Israeli airstrikes on Gaza amid a fresh round of violence in the besieged enclave, which the world blames on the Israeli forces.
Deadly clashes have accompanied major protests along the Gaza-Israel border that began on March 30.
The Gaza Health Ministry said two of the fatalities included a pregnant Palestinian woman and her 18-month-old child, another victim was a Palestinian man.
The statement of the Israeli army and the Israeli television "Reshet Kan" also said that more than 200 rockets were fired from the Gaza Strip into southern Israel. The Palestinian protesters have been demanding the right to return for those driven out of their homeland by Israeli wars and other acts of aggression since 1948.
Israeli military spokesman Lt. Col. Jonathan Conricus said the operation was "not meant to kill or abduct terrorists but to strengthen Israeli security".
