French President Francois Hollande warned Indonesia on Wednesday that the execution of a Frenchman for drug offenses would damage ties between the two nations.

Foreign Minister Laurent Fabius summoned the Indonesian ambassador in Paris a day after Serge Atlaoui, 51, had an appeal rejected by Indonesia's Supreme Court, taking him closer to execution by firing squad for his role in a clandestine ecstasy lab near Jakarta.

France said Wednesday it had foiled a jihadist plot to attack a church after an Algerian who accidentally shot himself was found with a stash of weapons and documents mentioning Islamist militant groups.

The 24-year-old IT student Sid Ahmed Ghlam's plans were exposed purely by chance after he called an ambulance saying he had been shot during an armed robbery at his Paris home, prosecutor Francois Molins told journalists.

French far-right leader Marine Le Pen, named by U.S. Time magazine as one of the world's 100 most influential people, said Tuesday it was recognition that her party was on the rise.

Le Pen said it showed the National Front was being taken seriously internationally and that one day the once fringe protest party founded by her ageing father Jean-Marie could take power.

Maronite Patriarch Beshara al-Rahi stressed on Wednesday that the Lebanese rivals are united concerning the necessity to safeguard the country's coexistence and diversity, considering that the Christian martyrs increased the power of the Church and helped in spreading the religion.

“Lebanon is passing through a delicate situation... and despite the rift, the Lebanese are united regarding the importance of protecting coexistence, diversity and the country's openness,” al-Rahi said from Armenia, where he traveled to attend the centenary commemoration of the Armenian genocide.

She was only a few months old when Ottoman forces came to take away her Armenian father, but a century on Shamiram Sevak can still imagine her dad hugging her tightly to say goodbye.

Relatives of a Frenchman on death row in Indonesia for drug offenses begged President Francois Hollande and the European Union to save him after his appeal was rejected by the Supreme Court on Tuesday.

"Our family calls on President Francois Hollande and the European Union to do everything possible to save Serge Atlaoui from the firing squad," his brother Andre told AFP, describing their "dismay", "suffering" and "lack of understanding" at the court's decision.

French President Francois Hollande on Tuesday called for Europe "to go much further" in tackling the migrant crisis after a series of deadly disasters in the Mediterranean.

"The European summit on Thursday cannot be an ordinary summit where we take ordinary decisions," Hollande said ahead of the urgent meeting called after the latest migrant shipwreck saw 800 people drown in the Mediterranean.

French military police said Monday they had wrapped up an operation to recover debris from the crash site in the Alps where a Germanwings plane smashed into the mountainside, leaving 150 people dead.

A police source said pulverized fragments of the Airbus A320 were being stored in a hangar near the crash site and clean-up operations were now set to start, nearly a month after the crash.

Syrian President Bashar Assad said he had invited Hizbullah militants to fight alongside his regime but he denied the presence of Iranian troops in Syria in an interview with French television broadcast Monday.

Iran is Assad's main regional ally, and Tehran has acknowledged sending military advisers to assist his forces in their fight against rebels and jihadist militants.

French President Francois Hollande on Monday condemned the killing of at least 28 Ethiopian Christians in Libya, urging a peace deal to restore order in the conflict-ridden nation.

Hollande said in a statement he was outraged at the "abominable" murder shown in a video by the Islamic State (IS) group released Sunday.
