French President Francois Hollande called on Lebanese authorities Saturday to hold presidential elections in May as planned, regardless of the latest violence in Beirut that killed former Finance Minister Mohammed Shatah.

President Michel Suleiman's mandate runs out on May 25 and there are fears that a successor will be hard to find because of huge disagreements between the country's political camps.

The Palestinian Follow-Up Committee slammed on Saturday random accusations against Ain el-Hilweh refugees camp after the assassination of ex-Finance Minister and former Prime Minister Saad Hariri's adviser, Mohammed Shatah.

“The amount of accusations against the refugee camp after any crime that happens on Lebanese territories ahead of investigations” is unacceptable, the committee said in a statement after holding an urgent meeting.

A Beirut car bomb that killed an anti-Syria politician underscores how Lebanon has become a "microcosm of regional conflicts", with violence escalating as Damascus and its ally Tehran become more emboldened, analysts say.

The Lebanese army denied on Saturday that it had disclosed any information over the investigation into the car bomb attack that killed ex-Finance Minister Mohammed Shatah.

“The military command categorically denies that it had divulged any information on the ongoing investigation into the assassination of former Minister Mohammed Shatah,” it said in a communique.

Al-Mustaqbal movement leader Saad Hariri warned late Friday that the March 14 alliance could impose tougher conditions on the form of the new government after the assassination of former Finance Minister Mohammed Shatah.

In remarks to LBCI TV station, the former prime minister said: “We were asking for a neutral cabinet, but now we could call for … (the formation of) a government (made up) of March 14” figures.
