Hizbullah MP Nawaf Moussawi criticized on Monday calls for the U.N. Security Council to discuss the setting up of “humanitarian corridors” to allow an aid group to reach areas hit with the Syrian army crackdown.

“Where were these humanitarian corridors to aid the Palestinian people in Gaza that is still suffering from the (Israeli) siege?” Moussawi said.

Attackers daubed death threats on the walls of the Baptist House church in central Jerusalem overnight and vandalized three cars parked nearby in the latest "price tag" hate crime, police said on Monday.

"Anti-Christian graffiti was found on the walls of the Baptist church and the tyres of three cars parked nearby were slashed," said police spokesman Micky Rosenfeld of the church which is located on Narkis Street in west Jerusalem.

The top U.S. military commander said Sunday he believed it would be "premature" to take military action against Iran in response to its nuclear program, as Britain urged Israel to give the diplomatic route a chance to succeed.

Iran may be preparing to expand its nuclear program at an underground plant near the city of Qom, a diplomat has told the BBC, just days ahead of a visit by United Nations nuclear inspectors.

Israel will ultimately decree on an Iranian strike on its own, its military chief of staff said in an interview broadcast Saturday, as a senior U.S. official arrived for talks on the Islamic Republic.
