The National Resistance Brigades announced April 2 that the ceasefire was over in the Gaza Strip, following an overnight Israeli air-strike that killed three leaders of Hamas' armed wing. The brigades, military wing of the Democratic Front for the Liberation of Palestine, said they would retaliate to the killings and that Israel "would have to bear the repercussions of this crime."

Israel's Knesset on March 28 passed a law enabling the judicial system to revoke the citizenship of anyone convicted of terrorism, espionage, treason or helping the enemy during times of war. The bill, which was passed by 37-11 in a late-night session, was initiated by two Knesset members from the ultra-nationalist Yisrael Beitenu party of Israeli Foreign Minister Avigdor Lieberman. "Without loyalty, there can be no citizenship," Lieberman said just minutes after the bill was passed. "Any person who harms the country cannot enjoy the benefits of citizenship and its fruit." The law is part of Lieberman's "no loyalty, no citizenship" campaign, which is widely understood to target Israel's Arab minority.

Evacuation and demolition orders were handed out to a Bedouin family east of Tubas on March 27, local officials told Ma'an News Agency. The orders come amid concern from UNRWA officials who noted a near two-fold increase in home demolitions during the first two months of 2011. Nabil Mustafa Daraghmeh, the head of a Bedouin family in the Ein Al-Hilwa area outside of Tubas in the northern West Bank, was served papers demanding he and his family evacuate their tent home and move their herds elsewhere. Palestinian security officials said several Israeli military patrol cars arrived in the area to serve the papers, which gave Daraghmeh one day to leave the area.

For a third day in a row, Israeli forces appeared in large numbers around the southern West Bank town of Beit Ummar March 28, installing road gates and fence posts in a move residents fear will close them in and stifle the population center. Local activist Mohammad Ayyad Awad told Ma'an News Agency that the installation of the infrastructure is impeding freedom of movement in the town, saying residents with cars were not permitted entry and exit for most of the day. Awwad said the installations were part of Israeli military preparations to fence the town in, and prevent residents from accessing the surrounding areas.

Israeli warplanes carried out a series of airstrikes on targets in Gaza City late March 24, injuring one person, witnesses and medical personnel said. Drones fired four missiles at the Palestinian Authority intelligence headquarters and an Al-Qassam Brigades site. Warplanes carried out raids on an agricultural area east of Beit Hanoun and four artillery shells were fired around the Karni crossing. One young man was injured by shrapnel, medical sources said. He was taken to Ash-Shifa Hospital for treatment of light wounds. An Israeli military spokeswoman said the airstrikes targeted a "terror activity site" in northern Gaza. The attack came in response to the barrage of projectiles fired at Israel in the past week, she added. (Maan News Agency, March 23)

An Israeli woman critically wounded when a bomb ripped through a bus near Jerusalem's central bus station on March 23 died of her injuries after being hospitalized. The attack was the first major bombing in Jerusalem since 2004. More recent deadly attacks involved gunmen, as in the case of the Mercaz Harav attack in March 2008 that left eight yeshiva students dead, or Palestinians commandeering bulldozers or cars and using them as weapons.

Israeli warplanes targeted sites across the Gaza Strip late March 21, injuring at least 17 people including seven children, witnesses and medics said. Ten people arrived at Ash-Shifa Hospital in Gaza City and seven others were taken to Kamal Adwan Hospital in the north. An airstrike in the Zeitoun neighborhood of Gaza City caused considerable damage but no injuries, residents said. An Israeli military spokesman said that the attack targeted two "terror tunnels, two weapons manufacturing and storage facilities, and two additional terror activities sites." The official emphasized that the attack came in response to the barrage of projectiles fired toward Israeli territory over the past week, including 50 on March 19 for which Hamas claimed responsibility. Among the targets were a police post and a training facility of Hamas' military wing, the al-Qassam Brigades, which a day earlier offered to stop cross-border fire into Israel if the Israelis halted attacks on Gaza.

Hamas' armed wing said March 21 that it would commit to a truce if Israel stops bombarding the Gaza Strip. However, the al-Qassam Brigades vowed to resist if Israel continued to attack the enclave. Brigades spokesman Abu Obeida said the group had fired mortars into the Western Negev on March 19 in response to Israeli aggression. Three days earlier, two of its members were killed in an Israeli air strike. The call for a ceasefire came as Israeli warplanes struck garages by a mosque east of Ash-Shuja'iyeh near Gaza City. No injuries were reported, but residents said Israeli fighter jets were circling above the besieged strip.
