BEIRUT - The Lebanese army said on Saturday it had arrested five Syrian men found with explosives and suspected of planning an attack on a Shi'ite Muslim procession on Sunday.
The war in neighboring Syria, pitting majority Sunni Muslim rebels against President Bashar Assad's inner circle of Alawites - an offshoot of Shi'ite Islam - has widened rifts in Lebanon, still politically divided along sectarian lines deepened by its own 15-year civil war.
Lebanon's Shi'ite militant group Hezbollah has sided with Assad and anger is growing among Sunnis and other groups sympathetic to the Syrian opposition.
The arrests in the southern town of Nabatiyeh followed an army raid on a house where 450 grams of explosives were discovered, the army said. The men were believed to have been planning to attack a procession in the town on Sunday to mark the Shi'ite festival of Ashura.
"The five Syrians have been living in Lebanon for years. They are thought to have been planning an attack on Shi'ites," a source said on condition of anonymity.
Shi'ites across the country hold rallies during Ashura but Nabatiyeh is one of the few places where Shi'ites observe the tradition of drawing blood by self-flagellation.
Ashura marks the killing of Imam Hussein bin Ali, grandson of the Prophet Muhammad, at the battle of Kerbala in Iraq in 680, in the culmination of a power struggle that ushered in the Sunni-Shi'ite divide which still shapes the Middle East's political map.
Meanwhile, a roadside bomb killed at least seven people near a Shi'ite procession in Pakistan on Saturday, police said, with security forces on high alert over fears of large-scale sectarian attacks on the minority sect across the country.
Pakistan, a nuclear-armed US ally, is suspending phone coverage in many cities this weekend after a series of bomb attacks on Shi'ites triggered by mobile phones.
Hardline Sunnis have threatened more attacks as the Shi'ite mourning month of Muharram comes to a climax. More than a dozen people have already been killed this week observing Muharram.
In Pakistan's biggest city Karachi, more than 5,000 police are expected to patrol the streets during Muharram events over the next two days. Tens of thousands are expected to take part in processions in Islamabad.
