London: After the death of al Qaeda No 2 Abu Yahya al-Libi, analysts say the Egyptian surgeon known as "Dr Death" must see himself as the next target.
"He (Ayman al-Zawahiri) and what remains of the leadership must be shivering in their sandals. There are no longer any safe havens," The Sun quoted terror expert Chris Dobson, as saying.
Al-Libi died in a missile attack by the US on his hideout in Pakistan`s North Waziristan region on Tuesday. Ayman al-Zawahiri, considered the "operational brains" behind the 9/11 atrocities, is also thought to be in the South Asian country.
Libyan-born al-Libi was the seventh major terror chief killed by a drone strike in Pakistan in a year. The US said it was "another serious blow to core al Qaeda".
Meanwhile, a bombing at the US diplomatic mission in Benghazi, Libya, was thought to be in retaliation. However, no one has been hurt.
