A bomb in Lebanon has wounded at least three U.N. peacekeepers, the second blast to target a U.N. convoy in as many months.
Lebanese security officials said Tuesday's blast rocked the entrance of the southern port of Sidon as a U.N. patrol with French peacekeepers drove past. Rescue teams had to evacuate at least one of the peacekeepers to the hospital.
A similar attack near Sidon in May wounded six Italian U.N. peacekeepers.
A U.N. peacekeeping force of about 12,000 soldiers and 1,000 civilians is deployed in southern Lebanon to monitor the border with Israel following the 2006 Israel-Hezbollah war.
The country has experienced turmoil since January concerning a U.N.-backed tribunal investigating the 2005 assassination of former Lebanese Prime Minister Rafik Hariri.
A Hezbollah-led group withdrew from the prime minister's national unity Cabinet that month due to disagreements about the tribunal's investigation.
Hezbollah denies involvement in the killing.
The U.N.-backed court handed indictments and arrest warrants in the case to Lebanon in late June.
Lebanese officials say the documents accuse members of the Iranian-backed Hezbollah militant group of carrying out the assassination.
