European Union's top diplomat Josep Borrell said Tuesday he would seek more information from Beirut, where he just traveled from, as he came before journalists just after news broke from Lebanon of several hundred people being wounded by pagers exploding, including members of Hezbollah.

Suspicion immediately fell on Israel, which earlier Tuesday stressed that halting Hezbollah's attacks on Israel's north to allow residents to return to their homes was now an official war goal.

Borrell acknowledged the exploding pagers could escalate the already-boiling tensions in the region.

"Certainly there is the possibility of the war spilling over to Lebanon," Borrell said.
