Blinken reaffirms two-state solution ahead of Israeli-Palestinian visit

US Secretary of State Antony Blinken said he would urge Israelis and Palestinians to calm tensions as he visits on Monday during the worst violence in years, and reaffirmed a long-stalled peace vision as the "only path" forward.

In new bloodshed, Palestinian officials said Israeli troops killed a 26-year-old man at a checkpoint in the occupied West Bank. The army said troops opened fire on the man's car after he rammed into one of them and attempted to flee an inspection.

Israel is on high alert after a Palestinian opened fire in a street outside a synagogue on Friday, killing seven people in the worst such attack in the Jerusalem area for over a decade. That followed an Israeli raid on the West Bank town of Jenin on Thursday in which 10 Palestinians, mostly gunmen, were killed.

"There is no question that this is a very difficult moment," Blinken told reporters in Cairo before departing for Tel Aviv. "We have seen, over many months, rising violence that is affecting so many."

In meetings with Israeli Prime Minister Benjamin Netanyahu and Palestinian President Mahmoud Abbas, Blinken said, "we will be ... encouraging the parties to take steps to calm things down, to de-escalate tensions."

The last round of US-sponsored talks on founding a Palestinian state alongside Israel stalled in 2014.

Netanyahu's new hardline government includes partners who oppose Palestinian statehood, and control over the Palestinian territories is divided between Abbas, who favours diplomacy, and rival Hamas Islamists who are sworn to Israel's destruction.

Such incidents occur regularly without attracting much notice. But in the current climate, they have added to the potential for the violence to worsen.
