Yemen's Interior Ministry stepped up security measures in Sanaa following an attack by suspected al-Qaeda members on a bus carrying members of the Political Security agency that left two dead and eight wounded Saturday.
Security patrols and checkpoints went on high alert to detain those wanted by security officials and intercept suspicious vehicles.
The Saturday attack was the first in Sanaa since the targeting of the British ambassador in April 2010.
In a speech delivered Sunday to mark the 48th anniversary of the Yemeni revolution, President Ali Abdullah Saleh expressed determination to fight al-Qaeda.
"Terrorism is a scourge afflicting the world, and we are committed to the war on terrorism out of national conviction. We have a responsibility to deal with this threat, which has damaged our national economy and damaged the reputation of our religion and our country," he said.
He added, "The wayward extremist and terrorist elements from al-Qaeda serve as their own worst enemy to their religion and their homeland. They harmed the interests of the people and the country. They impede development and damage tourism and investment in our country. They wreaked havoc in the land, which inevitably must be confronted and overcome by all means so that the truth prevails and dishonesty is eliminated to safeguard the country and the people and protect life."
Saleh said the security agencies are determined to eradicate the roots of terrorism and establish security.
"The president linked fighting terrorism to national duty, saying the state would perform its duty until the last breath and that it is a national duty, indicating a call for citizens to help make the security campaigns and fight against al-Qaeda and terrorism a success," political analyst Ahmed Sufi told Al-Shorfa. "The call transcends state borders as it serves as a moral, religious and national call to fight al-Qaeda."
Political analyst Mohamed al-Gaberi told Al-Shorfa that al-Qaeda, and terrorism in general, have no homeland or religion. "Their war is one where groups carry out destructive acts without a goal or strategy, and this factor helps the state in eradicating them," he said.
He said Yemen's success in fighting terrorism hinges on ending political, economic and social crises, which create an environment that is conducive to terrorism.
Political analyst Saeed Abdul Momin said that terrorism and corruption are two sides of the same coin.
"The state must create real development and work to combat poverty and fight against the corrupt who are looting Yemen's wealth. Then we can talk about a real and successful fight against terrorism," he said.
