Circus performers around the world are mobilizing in support of a Palestinian clown held by Israel without trial for more than three months on unspecified grounds.

They are showing solidarity with red noses and fluorescent wigs in Europe and with a colorful caravan outside an Israeli prison.

Israeli Defense Minister Moshe Yaalon said Thursday that the deadly bombings in Brussels are evidence of a new world war, which the Jewish state and other countries must fight together.

"We're in the same boat," he told Israeli army radio in an interview.

An Israeli soldier was detained Thursday after allegedly shooting a wounded Palestinian assailant in the head and killing him as he lay on the ground, with a video of the incident spreading widely online.

The video threatened to further inflame tensions amid a wave of violence that erupted in October.

Israel's intelligence minister accused Belgian leaders of laxity Wednesday over the threat posed by homegrown Muslim radicals, the second cabinet member to hit out after the deadly bombings in Brussels.

"If in Belgium they continue to eat chocolate, enjoy life and parade as great liberals and democrats while not taking account of the fact that some of the Muslims who are there are organizing acts of terror, they will not be able to fight against them," Yisrael Katz told public radio.

The Palestinian government has announced products from five Israeli companies will be prevented from entering the occupied West Bank, calling it a response to a similar decision by the Jewish state.

"In response to the Israeli decision to ban the entry to Jerusalem of products from five Palestinian companies, the government decided to ban the entry of products from five Israeli companies" to the West Bank, a statement issued after the weekly cabinet meeting on Tuesday said.

An Israeli minister on Tuesday suggested Europeans had ignored the danger of "Islamic terror cells" and focused on criticizing Israel instead, in a statement in response to the Brussels attacks.

While offering condolences over the deadly bombings, Science, Technology and Space Minister Ofir Akunis also hit out at Europe over its labeling of products from Israeli settlements in the occupied territories.

Hillary Clinton launched a withering attack on Republican frontrunner Donald Trump Monday at an appearance before thousands of Jewish voters, saying America's next president cannot be "neutral" when it comes to Israel.

Clinton's broadside, in which she implored to the crowd, "If you see a bully, stand up to him," comes as perhaps hundreds of people attending Washington's most influential pro-Israel lobby's annual conference, including rabbis, plan to walk out in protest when Trump takes the stage.

The U.N. expert on human rights in the occupied Palestinian territories voiced scathing criticism of Israel Monday as he stepped down over what he said was a lack of access to areas he was meant to monitor.

Makarim Wibisono, who took on the role of Special Rapporteur on the rights situation in the Palestinian territories in June 2014, presented his final report to the U.N. Human Rights Council, criticizing Israel's refusal to cooperate with his mandate.

Israel's government on Sunday warned against travel to Turkey after three of its citizens were killed in an Istanbul suicide bombing the previous day.

The country's anti-terrorism office raised its threat assessment and "recommends avoiding visits to Turkey," it said in a statement.

A Palestinian tried to stab Israeli soldiers in the occupied West Bank on Friday before being shot dead, the army said, the latest in a months-long wave of violence.

"An assailant, armed with a knife, exited his vehicle and charged at the soldiers guarding the (Gush Etzion) junction," an army statement said, referring to a popular road crossing near Hebron in the southern West Bank.
