The Yemeni capital Sana'a was calm on Monday, residents said, after armed tribesmen agreed to a ceasefire with government forces and President Ali Abdullah Saleh stayed in Saudi Arabia to recover, DPA reported.
Saleh underwent an operation in the military hospital in Riyadh on Sunday to remove a piece of shrapnel which became lodged near his heart during an attack on the presidential palace in Sana'a on Friday.
"We heard few gunshots overnight, but now it is very quiet compared to last week," Ibrahim Mothana, an activist in Sana'a said.
Leaders of the Hashid tribe, meanwhile, said they would abide by a ceasefire agreement as requested by Saleh's deputy and acting president, Abed Rabbo Mansur.
The ceasefire aims to end street fighting between security forces and supporters of Hashid tribal leader Sadiq al-Ahmar, who endorsed growing country-wide protests calling for Saleh's ouster.
One soldier was killed and 10 injured when gunmen attacked their checkpoint overnight in western Sana'a, News Yemen reported.
Fighting between government security forces and al-Ahmar's supporters broke out in Sana'a last month, after Saleh refused to sign a power transfer deal for a third time.
The violence, which lasted for weeks and killed dozens of people, stopped briefly during a ceasefire in late May. The ceasefire ended however with no official explanation.
