BEIT LAHIYA, Gaza Strip - Mideast envoy Tony Blair on Tuesday called off what would have been the first visit of a top Western diplomat to Hamas-ruled Gaza, citing a "specific security threat."
The former British prime minister's visit Tuesday was to have included a tour of a Gaza wastewater project and meetings with traders and UN officials, but not with leaders of Hamas, the Islamic militant group that seized Gaza by force more than a year ago.
Still, Hamas had made security arrangements for Blair, setting up checkpoints in areas he was expected to tour, banning cars from using roads and lining streets with black-clad policemen carrying AK-47s.
Since the Hamas takeover, Gaza has been virtually sealed off from the world by Israel and Egypt, a policy that has received tacit international backing.
Blair has said in recent weeks that a new policy toward Gaza needs to be developed, pointing to the growing suffering of Gaza's people, but has not offered a plan. The options are limited because much of the international community considers Hamas a terrorist group and has shunned its government.
Blair's spokesman, Matthew Doyle, said the envoy called off the visit "due to a specific security threat which would have made it irresponsible to proceed, not just for those visiting but also the local community.''
"He looks forward to being able to go to Gaza again in the future and will of course in the meantime continue to work to improve the conditions for the people there,'' Doyle said.
Taher Nunu, a Hamas government spokesman denied there were any security threats against Blair. "Gaza is still open for all visitors, to break the siege and see the extent of suffering here,'' he said.
Although the once lawless Gaza has been mostly pacified under Hamas' stern rule, there are still shadowy extremist Muslim groups in the territory. On an Islamist forum popular with Gaza residents, some users slammed Blair's expected visit, but there were no direct threats of violence against him. Those comments were later removed from the website.
Blair, a former British prime minister, is trying to revive the struggling Palestinian economy to lay the groundwork for a future independent Palestinian state. He represents the Mideast Quartet -- the U.S., Russia, the EU and the United Nations -- which is trying to push the Palestinians and Israel toward a peace agreement.
Blair also canceled a visit to Sderot expected on Tuesday, a town in southern Israel which is the frequent target of rockets fired by Palestinian militants in Gaza.
