(CNN) -- One suspect has been arrested in connection to a pair of car bombings that killed at least 45 people in northern Lebanon, the state-run National News Agency reported. Shiekh Ahmed al-Ghareeb was seen on surveillance camera in Al-Salam mosque in the site of the explosion. Security forces raided his home in Al-Minye and seized some military machine guns and some grenades, according to the news agency. The blasts Friday in Tripoli occurred near mosques run by Sunni imams with ties to Syrian rebels. While some Lebanese Sunnis have gone to neighboring Syria to fight alongside those trying to unseat President Bashar al-Assad's government, Shiites from Lebanon's Hezbollah group are fighting in support of the embattled leader.
